Roaming Symbol Problem

I just recently bought a Rogers HTC Magic, rooted the phone, and unlocked it. Everything seems to work completely fine. At the moment however, I seem to be having an issue with a Bell Mobility sim card. Bell's HSPA sim works fine, and I seem to be able to use voice and data ok, but the problem lies in that their seems to be a roaming symbol ("R") on my reception bar. Im using the phone in my local calling area which is somewhat misleading to me.
Im using MyHero 2.0.5 ROM at the moment. Does anyone know why this is happening? Thanks in advance!

Agreed
I'm doing the same thing. I'm running cyanogens roms and I get the same thing. Best I can tell is that this is normal on the magic. Just be careful if you live near the border like I do.

I figured this was normal too. I guess i'll try other SIM cards to see what they say as well, thanks!

Ya I also have this phone running on Bell, wish I could get rid of the roaming. It also asks if I want to connect once in a while too.

Shouldn't the romaing be dictated by the sim? I have a bell sim, on the bell network, why do I get the roaming icon? is there a way to change the phone so it doesn't think it's a rogers and not roaming or something?

Are you sure you have the Bell APN Settings and not the Rogers Settings in the phone?
Settings -> Wireless Control -> Mobile Network Settings -> Access Point Names
If it says Rogers you're Roaming on the Rogers Network.

I put in the bell APN. I don't think we can even roam on rogers network, wouldn't work. Either way, it's the Bell APN.

I don't have a clue as to the differences between Bell and Rogers sims... but I can tell you that my HTC Magic, on Rogers, with a Rogers sim (duh), running Amon_RA's most excellent RAv1.6.2H only shows roaming when actually roaming.
I was in the US yesterday and watched it flip from a Rogers tower to ATT. I was watching to make sure it was not using any data when roaming on a US network. The symbol, lockscreen info and the carrier listed in the status pulldown all were updated correctly.
It might have something to do with the ROM you are running. However I bet that given the phone came from Rogers, it has some carrier info buried somewhere that it is comparing to the carrier you are on (Bell) and triggering the roaming status.
If you disable data when roaming in the settings menu, what does it do? If it disables data, then the phone thinks it is roaming, which would support my carrier data mixup theory.

I will try a different rom on the phone. Unless someone knows for sure what I can do to fix this.
If you disable roaming there is no data, because once in a while it prompts to connect, if you say no, you get nothing. Sometimes my wife must accidentally hit no (its her phone, she probably says no cause shes not sure what it does). I just want to make it so she does not get the prompt ever (settings are all set).

I have a rogers HTC Magic (unlocked) I'm using a fido sim, it thinks its roaming as-well but I have only fido apn settings. It only roams with certain roms and radio's. I can use alot of roms eg. cyanogen,Hero HOFO 308,GYD 2.1.1 without roaming but when I update radio and flash cursorsense roms it thinks it is roaming. I have to enable data roaming in order to get a 3G signal. as a fido user I dial *#123# to see if I'm in my local zone zone. A fido tech rep told me that most unlocked phones indicate roaming because of the phones hardware programing. The hard programing of the phones checks the sim and sees that it is using a diff sim card and starts indicating roaming when in fact you are not. A rogers salesman also told me the same thing. He said as long as your carrier is displayed on your phone homescreen then you are good.

I have the AT&T Tilt, not running the AT&T ROM. I've tested a few different SIM cards on my phone and here's what I've found:
Rogers: Roaming works correctly. In Canada, no roaming indicator, in the USA, roaming is indicated correctly.
Telus & Bell (HSPA): Roaming indicator always on.
I've heard that this may be due to the SIM card listing more than one Mobile Network Code: 302361, 302653, 302657 (original Telus CDMA networks, not compatible with the phone or any kind of SIM-based network so it's uncertain why it would be on the SIM card), PLUS the HSPA network code 302880. It's possible that the phone is not reading that far into the list on the SIM and therefore does not know that 302880 is a home network.

Tilt 2 Roaming Triangle and telus
I'm on Telus and have a Tilt2. The original ROM that came with the unit didn't show the roaming triangle. I have attached some screen captures of the ROM. I've attached a copy of the registry (Remove the .cab it was the only way I could get it to upload).
I'm now running Jackos rom and it does show the roaming triangle.
Hopefully somebody can find where the settings are located and hopefully it's contained in the registry.

Have the same problem on the Stocks ROGERS 1.5 Rom. Sales associate said you should not get roaming charges since you aren't actually roaming and if you do, just contact your phone provider.

rogers htc dream unlocked now on roaming?
i also have a htc dream from rogers unlocked not rooted and my bell sims card works like my phone calls and my text but i can't get my data to work and when i click on the apns theres not thing and i am not able to adjust anything in there, if anyone can help it would be great, so pretty much the bell sims card works but i cant use my data and it says im roaming

If you aren't outside of Canada and you get the roaming symbol; they can not charge you roaming fees.

Roger and Telus PLMN Compared
I'm not sure if this will help,
I have attached a picture of the PLMN from a Rogers sim and a Telus sim
Maybe someone knows how to adjust the information on these lists.

The phone companies in Canada must be less uptight about unlocked/rooted phones
If you asked those questions to a t-mobile or at&t rep, they would straight up refuse to talk to you
American cell phone companies are still stuck in the "Ma Bell" mentality, where everything that touches their network must be under their control

anyone figure out a fix? I'm having these roaming issues as well on the bell network with unlocked at&t phone.

I have Same probleme Here, Bell on a AT&T Tilt 2 phone, Always get Roaming message.
any registry edit or mod available to make it work without these message ?

I searched around to a fairly moderate extent and I have found many people with the same problem, yet I can't find any resolution to this issue.
I'm not even sure where the issue lays. Is it with the hardware/firmware? SIM card? Windows Mobile? Is it the rilphone.dll? or maybe some registry entry. Maybe it's on the Bell network side?
Someone told me they put a Rogers SIM into their Fuze and it didn't show up as roaming, yet when they put a Bell SIM in, it's back to roaming. So what's the difference between Bell and Rogers?
Here's a question for anyone who has this problem, when you boot android does it still show as roaming?

Optimus 7 and Tmobile

So, I just bought this phone - I like the way it looks, and I wanted to try out WP7.
Unfortunately, I'm not sure how to get it working with tmobile (I live in the US)
It's a LG E-900h, with the canadian telus firmware on it. What do I need to do if I want to use it with Tmobile?

Let's start with what is not working for you. Can you at least make phone calls? Give us some details.

phone calls
Nope - Can't make phone calls - right now, the phone tells me my SIM card is invalid (in settings/cellular, it says "no sim")
I assume this can be fixed - but the methods I've tried haven't worked (I've tried debranding via the engineering menu, and swapping to the tmobile network profile)
Is there anything else I should try?

Its odd that it says No SIM, I'd figure it would at least ask you for an unlock code. Are you sure you have the SIM in the correct way? If you put them in backwards, the phone won't read it.
If your phone then asks for an unlock code, you'll need to SIM unlock it.

From this post http://forum.xda-developers.com/showthread.php?p=9827632#post9827632 :
Unfortunately, LG Optimus 7 does not support AWS, hence it will not support 3G neither on T-Mobile USA nor Wind Mobile or Mobilicity (it will fall back to GSM/EDGE modes on T-Mobile and will always be in Wind Away zone roaming through Rogers if you were to use Wind Mobile SIM card).
Not to stop you short, but just a heads up I guess.
If you go into the MFG settings to change the network profile thare are a couple that show "TMU_US" thought I'm not sure if that's even TMobile or what carrier that would be or even which one to try. But good luck.

yep
I saw that thread before hand, and I was anticipating the 3g problem (a tmobile rep had told me this as well)
My issue is making phone calls ATM. everyone else says when you insert a foreign sim, it asks for an unlock code - which mine hasn't done yet. I did buy the phone used on ebay (the seller claimed it was unlocked).
Regardless - right now, it says invalid sim. I inserted it with the notched corner UP
**SURE ENOUGH - sim card was in backwards. it's working great now

Don't feel bad, I forgot about that, but I did the same thing.
So use to haveing it only fit one way that I didn't pay attention to the picture, but I got it working after a litle while too.
Let us know how the connections are working out for you.

I have a Telus LG Optimus 7 phone, bought an unlock code on eBay for $10. When going down to US I use a TMO SIM card, and I can confirm that phone works perfectly for 2/2.5G (GSM/EDGE), and doesn't work with TMO 3G (which is AWS, same as Wind Mobile and Mobilicity, like someone mentioned above). But luckily for me TM has a $2/day plan which offers unlimited calls/text/2G internet, which makes it perfect for 1-2 day intermittent trips across the border, EDGE speeds are just enough to have my e-mails coming and maps working. It would support full 3G on AT&T, but they don't have any good prepaid data plans - the only one they could offer was 100 mb for $20, which expires in 7 days.

optimus 3g
are you sure that there's no way to change settings in the engineering menu to make it work with Tmo's 3g?
Also - what do I need to do to update my optimus to the new build of wp7?

I'm absolutely certain - you can manually switch between supported frequencies: WCDMA 850 MHz, WCDMA 900 MHz, WCDMA 1800 MHz and WCDMA 1900 MHz, but the phone has no support for AWS 1700/2100 (unlike regular WCDMA, when uplink and downlink use channels from the same band, AWS is also using different band for upstream and downstream).

When you say "new build" what exactly do you mean? Which build do you currently have? Does Zune tell you that you have latest firmware?

Can I use my Glacier with Telus / Bell / Virgin Mobile Canada?

Hiya...
I have an unlocked Mytouch 4g (HTC Glacier). When I put my Virgin Mobile Canada (same network as Telus and Bell) SIM card in, none of the above three networks are available -- only AT&T, T-Mobile and some mystery network show up. I've tried various ROMs, including the latest MIUI, CM7 and CM9. I thought the Bell bands were supported. Do I need to flash a different radio, perhaps? Any leads greatly appreciated.
SsshirazzZ
ps. the SIM card is good. I can see the Bell network with the same card on an unlocked Samsung Skyrocket.

The bands don't seem to be the issue. GSM bands are 100% supported, and one of the 3G bands is supported (2100).

Thanks for your reply.
I just can't seem to get it it see the Telus/Bell/Virgin Mobile Canada network. It can see Rogers, AT&T and T-Mobile (I'm near the US border), but not what I want. I've tried flashing the Panache radio, as well as different ROMS (including T-Mobile's stock Gingerbread as well as stock Froyo). I've tried several different SIM cards just to see if any of them would show the network. I remembered that I had my phone only foreign-SIM card unlocked by T-Mobile so I purchased a proper unlock code cellunlocker.net, but I can't get the phone to prompt me for an unlock code since it wasn't on stock. That's why I tried flashing to stock, hoping that I could get a SIM card unlock prompt, to no avail. Perhaps that has something to do with the T-mobile foreign card unlock already having been done, irrespective of ROM? Anyhow, I somewhat suspect this might be the issue, as it's the only thing I can think of besides unsupported bands, which you say is not the issue, or radio, which I've already tried. (Panache runs on the Telus/Bell network too).
I'm at a loss. I've put in about 8 hours to salvage my $150 phone. Virgin Mobile is the only real well-priced option here on Vancouver Island offering 3G or better. Funny thing is, if I were to buy a new phone, I'd probably want the same one (it's for my wife), but I don't know if the issue is specific to my phone or if I'd get the same problem.
Any further thoughts or input would be *greatly* appreciated... this has been one of those truly hair-pulling experiences.
Shiraz

Turns out they *are* incompatible bands. I didn't read the specs properly enough.

Someone with a little more experience tell me what I'm doing wrong here please.

This is probably something silly and small but I'm pulling my hair out trying to fix this. I bought a G4 play XT1607 unlocked from Best Buy the other week. I also purchased a tracfone SIM activation kit. The kit had 2 sim cards, one GSM and one CDMA. Since I used Verizon service previous to my foray into prepaid plans, I activated the phone with the CDMA SIM card and registered the IMEI with Tracfone. Then I was able to successfully unlock the bootloader following the motorola official procedures, put on TWRP and flashed a LineageOS ROM w/ SU and OpenGAPPS. It worked fine for a couple of days and then *poof* my internet data would no longer connect at all. I rebooted several times and got nothing.
I then saw that there is some LTE/wifi handoff bug and I figured, no biggie, I'll swap my tracfone service to the GSM SIM and pop it in and it'll be good to go. Not so. At first, in fastboot, the screen was saying <Baseband not found> and I couldn't even place a phone call. The phone still doesn't seem to recognize the SIM card and doesn't show any cellular connectivity. I've tried flashing AOKP, LineageOS (both 7.1) and the stock 6.0.1 deodexed several times. I've tried this thread here and using it's 2.35-1 Radio file with the above ROMs which I installed using TWRP as well. None of this is seeming to work so I called Tracfone and they said it should be working and must be on my end. So following this I decided to go fully to flash fully back to stock. I used this file:
https://mirrors.lolinet.com/firmware/moto/harpia/official/RETUS/
and followed these directions
https://forum.xda-developers.com/g4-play/how-to/guide-return-to-stock-firmware-recovery-t3551797
Phone seems to be working fine other than not getting any kind of cellular signal. Even though it should be "factory fresh now" When I called tracfone they didn't seem to sure of themselves and told me it would activate within 2 hours and to call back if I had issues. It's been 4 hours now an dNo sign of signal. Did I mess something up here? Does tracfone need to do something on their send since this phone/IMEI was used previously on their service as CDMA? Or can I just "pop the new SD card and go" Or do I just need to add something like APN settings or similar to get what I have working? I don't want to call tracfone again if I don't have to because they didn't seem to know what to do when I explained it to them and sounded incredulous that one phone did both CDMA and GSM to begin with.
Can anyone help me? I'd like to use this GSM SIM card in my unlocked XT1607 (RETUS). This phone was previously on the same tracfone account with the same phone number but on their CDMA network. What gives? Is this something I messed up or tracfone needs to deal with?

I did some more research and I'm pretty sure this is on Tracfones end. I believe they still have it registered as a CDMA device and it's ignoring my GSM SIM when I turn it on.

I don't think that's the issue. Did you set an APN for Tracfone? With the GSM SIM, you have to configure the APN.
Tracfone's site says to go to apn.tracfone.com but that site gives an error. I did find this: http://apn-settings.com/tracfone-apn-settings-step-by-step-configuration-guide/
Or you can check on Howardforums or Turks.

Also G4 Play, also Tracfone BYOP. I, however, did GSM from the getgo to avoid something like this. On my phone, when I installed Lineage, my MEID disappeared entirely (it only shows my IMEI in settings). SIM card reads just fine and APN settings are fine. I do think the initial ROM you installed inhibited the device's ability to read its own MEID (everything hints at these ROMs being made specifically for dual-SIM GSM phones). However, switching to the GSM SIM should have worked, provided you actually transferred your number and didn't just pop the other SIM in (the MEID on the Red "BYOP" card would have needed to be decommissioned).
Here's a thought: Try dialing *22890 on the phone. If it says the phone is programmed for CDMA service, then that could be part of the issue. Also check Settings to see if you have both an MEID and IMEI, or just an IMEI. If your IMEI is 0, then the SIM Card is not being read and they need to ship you a new one.

SM-G975U1 - locked to Verizon Towers?

My situation... bought an 'unlocked' S10+ from Amazon. When I put my ATT sim in it, I get a message:
"Sorry, your device can't be activated on another carrier's network right now. For help, contact Verizon...."
So - I talk to Verizon. The technician told me, yes, it is unlocked, but will only work on 'Verizon Towers' - and some stuff about cdma vs gsm sim cards? And that my phone (SM-G975U1) can only use cdma cards and verizon service? No ATT - No T-mobile.
Can I get some feedback on this from those (you!) that might know better - or be able to explain it to me a bit?
I thought **U1 phones were able to be used on anyone's network?
Thanks!

More info...
Under settings/mobile networks, my options are:
Global
LTE / CDMA
LTE / GSM / UMTS
I seem to be able to register/join att network - but no luck using the phone (no calls, no sms)
I do notice I only have an IMEI number in 'About phone' (and I read I'd have both EMEI and (MEID or an ESN) if my phone could do both... so, a little confused there.)

Also - I have flashed a couple firmwares to no avail...
G975U1UES6GUG1_G975U1OYM6GUG1_ATT (I think I skipped USERDATA - maybe I'll give that a try again)
G975U1UES6GUG1_G975U1OYM6GUG1_XAA
