T-Mobile SIM Lock

Hi,
I just bought a T-Mobile Pocket PC. It is locked onto T-Mobile and I want to use it on Cingular Wireless for a couple of days till my number is ported to T-Mobile in the next 5-6 days as I have been told.
Any solutions will be most appreciated but please understand it is a brand new unit I have bought after cooking the ROM on the old Siemens SX-56 still lying with me; and I really really don't want to mess this one up. It has Windows Mobile 2003 edition on it.
Thanks in advance for your help.

Before trying to unlock it, I would check that Cingular are NOT operating on the 850Mhz band in your area as they are in mine (Atlanta) As the XDA is only tri band, it will not work on Cingular's 850 network. Even if there are roaming options in your area, I have found that the Cingular SIM prevents roaming on 1900Mhz, when a native Cingular 850Mhz band is present.

Thanks for the reply. Yups, u're right but I wanted to use the phone in London and its ok since they have a 900Mhz bank there. Also, I spoke to T-Mobile and they will be sending me the unlocking code in 4-5 days, they are more helpful than Cingular in that way.

Ah, London!, my home town!! You may know this already, but in case not, here goes...
Before you go, make sure that T-Mobile USA have your account set up to make international calls. When you get there, you will have to manually change the band on your phone to pick up the 900Mhz band. Once you do that, the phone will probably connect to either the O2 or the Vodaphone network, as T-Mobile operates only on the 800 band over there.... You will of course be hit for some pretty hefty call charges, as all your calls (even to UK numbers) will be treated as international calls. It took me a couple of trips and a couple of $400 - $500 monthly invoices to get wise to what was going on. Then, once I had the phone unlocked, I switched to using an O2 Pay and Go SIM card whenever I am in the UK, leaving a message on my US TMO voice mail with the UK number if someone wanted to reach me. It saved me a lot of money when I finally figured it out.

Re:
Well my friend you saved me the trouble of figuring it out on myself and of course the huge amounts of un-justified spend dollars!!!
Thanks a bundle! I will take your advice and use the pay-to-go cards instead of my T-Mobile service, and leave the voice mail and I can as it is extract the voicemail from anywhere, unlike the Cingular voicemail which you cannot except just from your phone.

Great! glad to help A couple of other things spring to mind...
When you go into the O2 store to get the 'Pay and Go', see if they can also set you up for international calls. Its about a $3.00 one time activation fee. That way you will be able to dial back to the US with the Pay and Go SIM. Rates are about $1.50c a minute. You may have to phone O2 custmer service to activate it, buts its worth the trouble.
O2 will also give you a top up card that you can use at pretty much any gas, sorry, petrol station to top up your pay and go account. Just give the attendant the top up card, a credit card and tell them how much you want to add to your pay and go account. Its pretty slick!
Also, if you need to pull e-mail down from your US e-mail account, you can always just put the T-Mobile SIM back in and connect via GPRS through O2. I believe that there is a data option available with O2 Pay and Go as what they call one of their "bolt ons", but I never managed to get that done on my last trip. Anyway, have a good trip!!

Thanks a million!

Unlocking using Rebel SIM card II - mixed results :(

New information:
It turns out that my initial enthusiasm was unfounded.
I can confirm that Rebel firmware versions 1.1 and 1.2 produce an "invalid SIM" error. Version 1.3 beta and 1.0 work initially on 2G, but further testing reveals the following problems:
- incoming calls not always received, sometimes they go straight to voicemail
- call display shows "Unknown" for certain out-of-network callers
- phone will be connected to network for several hours, anywhere from 2 to 18, but once it loses signal it can't get back on until you pop out the SIM, put it in another phone WITHOUT the Rebel SIM, make a call, send a text, leave it for 15 minutes, and then try all over again
- based on my limited testing, you can't connect AT ALL to a 3G-only network (that is, Wind and Mobilicity in Canada)... this is consistent with reports about the Rebel SIM on Android devices having issues with 3G and needing to connect on 2G first
I am sorry to anyone who jumped at any purchases as a result of my previous test results. Personally, it is with great disappointment that I'm returning my Venue Pro to Dell.
I can now confirm the only method for SIM unlock of the Dell Venue Pro (locked to T-mobile US): buy the Rebel SIM II. You can use it with your non-Tmobile SIM to send and receive calls, SMS and data! But no MMS
You will need:
Rebel SIM II (http://rebelsimcard.com/virtu/index...s&flypage=flypage.tpl&product_id=445&Itemid=1)
Rebel Compact Programmer (http://rebelsimcard.com/virtu/index...ategory_id=243&option=com_virtuemart&Itemid=1)
You may also want to get the SIM cutter, which is just a fancy hole puncher - and if you're getting that, maybe one of the bundled options is best. But I used an exacto-knife to cut a notch in my SIM card.
Buy these and get them shipped to your house. (Mine took exactly one week to arrive from UK to Canada using Royal Mail, but I'm pretty close to a customs point of entry.) DHL and FedEx shipping options will be faster but more expensive.
The Rebel SIM II comes preloaded with firmware v1.2 - you will need to downgrade the firmware to v1 (http://rebelsimcard.com/virtu/images/downloads/rebel-II_v1.cardfm) using the USB compact programmer. Follow the instructions on Rebel SIM's site.
Go to cellular settings and manually select your network - it will take time to find it. Once that is connected, test out the calling and texting with a friend.
Now go back into cellular settings and click Add APN, filling in the data APN address, username and password for your carrier. After that, enable data roaming, and then enable the data connection.
EDIT: if you get booted off the network after a while, try reprogramming the Rebel SIM with firmware beta v1.3 - it worked for me after making one outgoing call and sending one text message

My experience
I'm on Rogers Canada - a network with 850/1900 MHz EDGE, and 850/1900 MHz UMTS/HSPA. Obviously I am stuck on 2G with the Venue Pro, but that's okay for now.
I ordered the above-listed products from Rebel SIM last week. I used an exacto-knife to cut a notch in the plastic end of my SIM card where the Rebel chip sticks up. Then I tried the whole thing with firmware v1.2 which comes pre-programmed on the phone, but I got an "Invalid SIM" message.
I programmed the Rebel SIM with firmware v1, and it has unlocked my Venue Pro. Now I can send/receive calls, texts, and data. I used the APN settings APN: internet.com , username: wapuser1 , password: wap . As soon as I enabled data roaming, a little "E" popped up beside my signal bars. Now I have cellular data. (EDIT: I had to switch the Rebel to beta firmware v1.3 after getting kicked off the network 18 hours later)
I'm not going to bother bugging T-mobile and Dell for an unlock code, like so many others have. Do you know why? Just look at the Dell Streak for AT&T - there are no unlock codes, and only one user (ONE!) was able to get it by talking to a string of different managers and escalating the problem through a lucky combination of people. Dell went on to sell the Streak through other global carriers and those people have been able to get unlock codes... but as far as I can tell, the only solution available for the AT&T-locked Dell Streak is Rebel SIM II. That, plus a mail-in service the same company has just started... basically they've found a way to crack the unlock code over USB.
I predict the same thing will happen with the Venue Pro. The European devices will eventually get unlock codes, either through their carriers or through third-party sites. But those of us who bought the first batch from Dell.com will be stuck with the Rebel SIM... until somebody finds a way to hack the Venue Pro into giving up its own unlock code directly.
Meantime, we can hope that the Euro-made DVP comes with some useful new software bits that we can extract as XAP files and sideload onto our devices... like an Auto Device Config (ADC) and/or MMS settings app. I can live without MMS until then.
Don't get me wrong - I think Dell's behaviour is totally wrong here. But they're a tough nut to crack, and plenty of Dell Streak users have come before us and faced the same disappointments. We're lucky the Rebel SIM works.

I am using a sim hack similar to RebelSim from my previous phone, (Sharp 904sh), and it works fine with Fido sim card. I'm able to make calls and all that on DVP. However, once I put the sim hack on Mobilicity's Sim card, it won't find the network. Under Network Selection, I can manually choose Mobilicity and CDN Roaming, but the Active Network always shows No Network no matter what I do, I am wondering if RebelSim works with Mobilicity Sim, or my Sim hack is not good enough

Thanks a lot dude
I'm ordering my Rebel SIM II right now

Will this work from t-mobile to ATT ?
I have the samsung but want to use the dell venue pro ?
and if so what bad could happen ? could I damage my sim that is in my Focus ?
if I try this and it does not work will tmobile stop working

I can confirm it works on ATT. For some reason my data isn't working properly, but it might just be my shoddy coverage right now. I will test it in other areas (non-residential) where the signal is better. APN settings are correct.

I have no idea - I'm no psychic and I don't work for Rebel SIM! If you follow all instructions correctly (especially those on YouTube regarding the use of the USB SIM programmer; don't try to reprogram your AT&T SIM card) I don't see how anything bad could happen.
The whole point of the Rebel SIM is that it does absolutely nothing permanent or destructive to your phone or your SIM - it just interferes with the communication between the two of them.

benjaminries: Do you think you'll be able to test your RebelSim with Mobilicity Sim card?

EDGE works on ATT, no 3g obviously due to band differences.

If somebody in Toronto gives me a Mobilicy SIM and lets me cut a hole in the plastic part, sure.
Just to let everyone know: after about 18 hours working with the new Rebel SIM, my phone all of a sudden wouldn't connect to the network. Apparently this is a problem with the STK-based firmware.
So I troubleshooted for a while, and eventually decided to try the v1.3 beta firmware. It works for me - after I make an outgoing call and outgoing text, I can get incoming calls/texts... and data works too.
Go figure.

I've had continued problems with both v1 and v1.3 - and I tried out a Wind SIM card in-store, with utterly disasterous results (no connection). See first post for details.

Sucks to hear that I'll still be keeping mine if anything just for dev purposes and then getting an android phone with WIND if I have to.
No 3G even with Rogers?

There wouldn't be 3G with Rogers because Rogers uses 850/1900 for UMTS/HSPA. I think the underlying issue is that the Rebel SIM can't just jump straight onto a 3G network - it needs to try underlying 2G first.
I've still got a contract with Rogers that is up in December of this year, at which point I'd probably switch to Wind regardless. Dell tried to convince me that T-mobile would give me an unlock code after 90 days of service with them, but... I don't believe it enough to risk it. It is hard to even really get excited about the other WP7 devices... the HD7 is the only other AWS option, and the Samsung Focus seems like the only other half-decent WP7 available in North America.

Well I just got back to Canuckistan with mine, if anything I'm more pissed about the blurry camera/broken autofocus since it's ruined most of my shots while I was down in NYC.
If I didn't need it for dev purposes as well I'd be about as pissed as you are. No dice for me with the unlock code at Tmo for me either, although the staff were quite impressed by it and had never seen one before. Contrary to the many negative store clerk stories towards WP7 I've read elsewhere.
What is this 90 days of service thing, 90 days of a monthly plan? or just after 90 days if you've activated a TMo SIM, because I did do that while I was in NYC. Even my lowly $10 of credit went a lot further than any paygo plan in Canada, espec by Rogers' standards
Yeah it's a sad thing about the other WP7's as well, I'd have gotten a Focus if it was AWS compatible, at least the camera would work
So does the Rebel SIM work that way for all phones? it has to try 2G first? sadly the order for mine has just gone through

I dunno. I was only able to test the WIND SIM in-store with the Rebel loaded up on v1.3 - it may have worked with v1 in one of the 12 STK modes, but even then, the whole thing doesn't inspire much confidence. Even "working" meant that some people's calls to me didn't go through, some of the call display stuff didn't work, and getting booted off the cellular network after 12-18 hours was something I wasn't going to be able to test in-store either. In the end, I'm not willing to keep a phone with such problems.
If I hear of a way to properly unlock the Venue Pro, I will buy it back in a heartbeat. No other phone delivers what I grew to love about the DVP: portrait keyboard, gorilla glass screen, and WP7.

I've had Tmobile unlock 2 phones for me in the past without issue. As others have mentioned all that is required is that the phone remain active for at least 90 days. After the 90 days, they'll unlock the phone for you.
Now who knows if they have access to unlock codes for Dell phones.

[Q] tmobile and unlocked Samsung Tablet

I apologize because I think I may have posted my questionin the wrong place two days ago. I'll see if I can delete it. I hope a few people here can answer me.
My question is that I already have a voice data account with tmobile and SIM card for that account in my Galaxy S Vibrant. Can I remove the SIM from the vibrant and place it in this particular International unlocked P1000 Galaxy TAB to use this P1000 as phone and data just by moving the SIM card? Or do I have to still notify tmobile that I am moving the SIM to this unlocked P10000 device? And will all features of this international version then work....the phone and 3G data with my SIM from the working Vibrant? If I can just move the SIM card is there anything else that I have to know or have to do?

All US carriers consider Samsung Galaxy Tab as a mobile broadband data device and make difficult to walk around this decision.
Since you are going to get a Tab not from T-mobile, it will not have your IMEI number recorded and might treat your Tab as a phone allowing for both voice and data. The issue might be only that you will not get 3G for data because software and hardware do not support unique 1700/2100 AWS frequency bands utilized by T-mobile in the US.

Do you have the phone dialer icon? If not you will need to flash a rom so you have a dial pad.

Thank you both for some answers.
The reason I was looking at this imported version was because I read that this Samsung tab already allowed telephone and since I already had a working 3G and telephone SIM from tmobile I thought this was the way to go. I really wanted this Samsung Tab to do telephone so that was the real reason even looking at this particular item.
No I have not ordered this yet. I wanted to ask the questions BEFORE I paid the money to find out that it will not work in my situation?
So what I am reading from both of you is
1. I probably will not get 3G, and
2. I would need a dialer Icon from somewhere.
Not getting 3G is a "do not purchase this" issue then for me.
Any ideas on the Samsung Tab then? I do NOT mind signing it up with tmobile, I just also wanted it to do bluetooth phone, 3G and then only need to carry this one device.
You guys are great
Thank You

The T-mobile tab can be unlocked. After it is unlocked you can flash it with a European rom and Roto's modem swithcher. You can then run 3G on any carriers sim card and switch to 2g (edge) and phone with T-Mobile using Roto's modem switcher.

WoW. Thanks for that info.
Wonder if you do all this and will hear incoming calls if you are in 3G mode. (i guess this is what the Roto's switcher does, it places it in 2G or 3G). Then if you could/would hear it ring while in 3G, for an incoming call you would then have to switch to the 3G mode with this Roto switcher? Trying to get the call before voice mail kicks in? (what is it, an icon for an on-off type thing of its installed software).
Has anyone actually done any of this?

Yes its been done by many Tab owners. Search the galaxy tab developers section for how to flash roms, modems and kernals. You'll find a treasure trove of information on how to improve the Galaxy tab. The Developers here at XDA are an incredible group of people and most are willing to share their development findings with other Tab owners.
Good Luck.

Do I understand you correctly saying that T-mobile Tab after flashing can get 3G and voice phone on any carrier Sim?
This would be my "dream". So far I can only get either voice with phone Sim or 3G data without phone capability. BTW, the latter requires Sim with paid data service separate from smartphone. Roto's swither is just a utility flashing either phone modem or 3G data modem.
Would you mind to give more details supporting your post.
P.S. European Tabs have phone voice capability and a dialer out of box. Not extra flashing is needed.

Voice + EDGE data OR OR OR 3g data/ no voice NOT NOT NOT both!!

You cannot get 3G data and voice at the same time on the Galaxy Tab. With the modem switcher you can switch between 3G data only and 2G (edge) data and voice.
Until the development community can come up with a method to run 3G data and voice at the same time (if possible) the modem switcher is the best answer to the problem.
Also the the T-Mobile Tab can be unlocked so that any GSM carrier's sim card can be used. This allows you use the sim cards from Simplemobile or any other GSM carrier and not be locked into a T-Mobile sim card.

Anyone live here in MD and want to make some money setting me up doing this thread hack/install for me?

I am a T-Mobile customer and here is set up on my T-Mobile tab:
1.Tab running Roto's JME v4 (European firmware that will allow voice+edge)
2. Roto's Modem Switcher (switch between 3G only or Voice+Edge)
3. My old Vibrant SIM card (Voice+Data)
4. Broke IMEI so i could use my Vibrant SIM to go online and stop getting re-directed to t-mobile site.
So basically i use my tab as a phone now but only getting voice+edge, if i want faster speeds i switch over to 3G using the Modem Switcher. The only way you can get both voice+3g is if you unlock the tab and use AT&T sim, if you want to use T-Mobile sim that option is not available unless a modem comes out that allows both voice+3g.
Hope this helps in making your decision.

Hello and thanks very much,
Seems that you are a match to my scenario. Are you happy with everything the way it works now (voice/2Gdata).
Do you have Caller ID working in any setting/switch?
And to make sure I understand this part. If I am in 3G mode I will NOT ever know of an incoming call by any pop up or beep or anything? The only way to know if some one even tried to call is to go to voice mail from 2G/voice being switched? (se, I am not a voice mail user. i have my Vibrant tmobile voice mail turned off at tmobile.)
So what i read at the top of this thread about having to unlock it is not the case for me?
Do I have to remove anything or add anything else?
Having to do anything at all other than these 4 things you listed for me is not needed?
That's very interesting. How do you "break" IMEI?
And these installs that you did list, is this the exact order to do these things?
And what about the thing where someone said I need a phone icon?
How do you switch to phone mode and dial?
BTW how is it as a phone with Bluetooth device? How is the volume (at both ends). Can you hear okay?
And I think one last question. If you happen to be in a wifi spot and using the tab in wifi mode, does the phone work at all?

No true. If you flash the at&t tab with Roto firmware, and install the bell modem, you can have 3g and voice with an at&t sim card, but again, at&t tab only does this.

Dear noreturn
If you so eager to get it and need help send me PM. I am almost your neighbor.
I would not recommend you breaking (meaning erasing file containing) Imei.
You have two other options
- get At&T tab, unlock it use on Tmobile with Vibrant sim. You will get voice and Edge which is very usable around dc-md-va. 3g will be only on att.
- get European Tab that is unlocked and use it on same way as #1 but no extra firmware flashing is needed.
Unlocking of either Att or Tmobile Tab is easy the same is true about flashing. however it takes more time.
Caller id works as on any phone.

Yes I really do want to get this samsung with voice.
So are you saying get this version of the Samsung tab and use my tmobile vibrant SIM?
Then install that modem switcher thing is all? And I guess I read about a dialer icon or something?

European Tab has everything for voice and Edge but Tmobile tab just cheaper.
Dialer comes installed with European, on Tmobile it appears after flashing.
Hope you understand your options. Modem switcher helps only if you have paid data service or erased your Imei. The last case is legally questionable thats why I would not advise it.

True. I should have clarified my response in that I was referring to the T-Mobile version.

I have the Hong Kong version,which has the same 3G frequence with At&t.
I use a At&T sim card and has 3G or H on phone and data works perfect.
For t mobile sim card you will only get edge for voice and data.
If you have any question you can email me.
Jimmy

Its kind of pricy,it cost me almost 700.00,but you don't have to change anything.
It depends on what carrier you use Tmobile 2G, AT&T 3G.
I love the device.you can hold it by one hand and use other hand to surf.

My New Nightmare Tablet

Picked up my Tablet yesterday from T-Mobile. Connected to the web etc using Wi-Fi because I had lots of software to download. Could NOT get any data with my sim card.
I am grandfathered into a data package with T-Mobile which gives me Unlimited Data for $19.99 plus a voice package. Support told me that for this tablet to work I had to upgrade to their Web Connect package for $39.95 and I would NOT have voice. [because they INSIST voice is IMPOSSIBLE with the Galaxy Tab.] [whatever]
I didn't want to agree to their upgrade because my sim works PERFECT in my Dell Streak 5 .. I believe that there is something wrong with the Gal-Tab. I kept telling them that the internet net was the same in their web connect package, it was just more expensive. They told me I was wrong. So I said .. OK make the change. They did and 12 hours later I still cannot connect.
I contacted them this morning and got them to give me my OLD $19.99 internet package and voice back ..
SO .. Any ideas ?? I even tried changing the APN on the Samsung to the same as on my streak. My streak is epc.mobile.com .. the Samsung had it as epc.tmobile.com

I had an issue with my data when I first got my tab too - the support personnel signed me up for an incorrect data package and all I got was a redirect to a Tmobile page when trying to use the browser (and no data on any other apps).
After talking to Support they changed my data package and voila, it worked.
So what's going on - unfortunately T-Mobile US filters Galaxy Tab's by IMEI. As such, they completely block it from working on any plan other than the data plan built for it. Despite the fact that the tab is technically capable of being a phone, T-Mobile will not allow it on their network.

So your telling me when I get my galaxy tab if I pop in my wifes T Mobile sim it wont work. That is truly annoying.
Instead of getting a new data package I am going to just pay the 10 a month to add mobile hot spot to her phone which will work great (maybe even faster because she has 4G on her phone)

THANKS .. I hate T-Mobile but have been with them for 8 years .. I guess I have just learned to put up with their NONSENSE !!

Since Dell Streak 5 came from AT&T Tmo does not have records and treats it as a smartphone. The same will be true for the Galaxy Tab purchased from AT&T. You will be able to get data and even voice using other Tmo Sim after reflashing proper firmware.
But since these two carriers use different frequencies for 3G you would get only EDGE.
It is hard for us to understand rational for such decisions. It seems that they are loosing Tab sales. Why do European carriers find it profitable while US not?

there is a way to get both voice+data on the tab using a standard t-mobile sim with data+voice. 1-you need to flash an European ROM to get voice and 2-then there is the issue of the IMEI which blocks the tab from accessing the web with a sim that already has data.
the second part cant really be posted as i was already removed by the mods due to rules violations, but it can be done i am using my Vibrants SIM on the tab.

Sounds like someone failed to do their homework. T-mo Tab is suppose to be data-only device and utilizes different APN's with custom modem firmware then smartphones, hence why your SIM would not work. You need to root the Tab, flash Euro firmware, then flash a custom modem. Instructions can be found in the development forum. Also, keep in mind that flashed T-Mo Tab can only get EDGE, no 3G.

That's not correct! You can get 3g data with your T-Mobile sim card with the correct modem. Just use roto-modem switcher

I think all our posts can confuse anyone.
The question was about using Tmobile smartphone Sim with the Tmobile Tab.
Let me say this: there is no way to get legitimely both voice and data on Tmo network using Tmo Sim. You can get voice without cellular data, or 3G data with different modem and separately paid broadband service Sim not the smartphone Sim.

I put my Sim card from my MyTouch 4G on the Tablet and phone works n/p but you need to flash a Euro rom! Thats it bottom line! Flash The rom and you will have phone access

Complete debrand of LG G6

I was wondering if like Sony and Samsung devices, if it's possible to completely debrand a G6 to enable Wifi calling and VoLTE on a specific network's branded software? I know the G5 left the original operator's customisation files (unless rooting to change the cust folder) but has this changed with the G6?
Haven't bought the phone yet but seen an unlocked one which obviously wouldn't have network branded software.
Thanks.

Not sure of the purpose of this. So you want a completely unbranded phone and then want to install a specific network's software for wifi calling and VoLTE? If so, why not buy the phone from that network? Example: I bought an unlocked T-Mobile phone (on Amazon, not directly from T-Mobile) that can be used on any network, but contained T-Mobile software. I disabled what I didn't need. I am on T-Mobile anyway so I can use their wifi calling app.

Purpose is that a second hand unlocked phone is much cheaper than one branded to the network at the moment.

wifi calling is mostly junk and over-rated feature. I know of no phones that can do a decent handoff in the event that wifi signal drops out of range then the phone wants to continue the call on LTE but if your LTE signal is already weak the call will just drop. Happened to me all the time so I just disable it and all the HD voice garbage too. Forcing back to the old 4G network thats now less congested than its ever been!

Admittedly wi-fi calling has only come in useful a handful of times, but the 4G calling feature has worked for me in a few places where 2G/3G is patchy. Guess I could do without it though.

Install Google Voice, hangouts, and hangouts dialer. Then you can use Wi-Fi or data calling in any phone or any rom.
I'm using a US997(16a) in Verizon and it works fine.

Thanks, had those installed on my G5 but never used them. Will give it a go.

I switched from an S7 Edge, on which I was able to change the CSC Code and get features different Canadian Carriers had to offer. The particular one I was interested in was VoLTE(Video/Voice over LTE) video calling was the main feature I wanted to keep. That's why when I switched to the G6, I made sure it was from Rogers so I can continue to use that feature. It's pretty sweet... great quality video calling without using any data
I wish LG had a feature like this too, where you can change carrier settings on unlocked phones. It would be helpful

It would indeed be helpful! I guess I managed fine without the features before and it's not a huge loss but wi-fi calling definitely came in handy at a couple of places I used to work at.
IME Samsung and Sony phones were fairly easy to fully change carrier firmwares on and I remember HTCs being a pain (not sure what they're like now). But LGs seem to be able to debrand 90% of the firmware but still leave enough of a trace of the original software to block off a couple of features, which is slightly annoying. Ah well
