I manged to buy an htc evo 4g from the us. Ofcourse I didin't know the phone was a sim free phone!=) Aniway..
Norway have all the net htc evo 4g needs to work accept 4g..
cdma,edge,turbo 3g,3g...(3gs) cdma 200 1rtt...
The problem is the sim card..but I refuse to think there isint't one guy here at the xda that cant mix something up!
Some how possible to like use a sim card reader and install the sim card in the phone some how..
after some reseach i understood the the sim card holds information that connect the phone to its operator as for me (telenor norway) so its possible to ring, send sms and mms.
so teoretlic it has to bee possible at least i hope..
really hope for some positive answer
Just to let you know, for CDMA it's not a SIM card, it's a RIM card.
Anyway I think let this be a lesson to you that CDMA phones sold in the States are NOT RIM-replaceable. Only a few countries in the world that will let you do that.
Your best bet? Well, if you know anybody that works for your CDMA provider, he/she maybe able to manually add the ESN into their network and... well, it's just way too much hassle. AAA Keys, provisioning and such...
Sadly I don't think it'll work in Norway. I've seen ppl made the Evo to work for China Unicom (Only CDMA provider there) with a LOT, I mean A LOT of work just to get the 1xRTT functions such as voice calls and such to work. No data... YET because they haven't figured a way out to change the AAA key.
As for 4G/WiMax? Well, not going to happen unless your country decided to use that technology. Most likely LTE will be used instead of WiMax, knowing rest of the Europe relies on GSM systems more than CDMA.
..
okay'
Telenor norway provide cdma so what you are sayng is that this is possible for the operator to mix som up(even thou it is to muchtrouble..).. but then again there would bee problem for htc evo 4g because its not rim card replaceble?
this vpn thing in the phone.. what is that for? is that for the wimax only?

Well it's not, not replaceable per se, it's part of the phone. See in other countries where using RIM on CDMA phone is practiced, the ESN is part of the RIM card. Just like MSID on the SIM card for GSM (correct me if I'm wrong). Imagine it's a GSM phone but the SIM card is permanently part of it.
So what you have to do is ask your provide to ADD your phone's ESN onto their network so it can be used onto the system. However that only solves the 1xRTT (voice and text), in terms of data (EvDO), it'll be harder due to the AAA key and such. Your provider is the one that makes the final decision.
As for 4G/WiMax? Well I don't think there is any WiMax network rolled out in your country. Even if there are, it'll need further tinkering due to preset configuration in the phone's WiMax part.
VPN has nothing to do with WiMax. VPN is an application and WiMax is a protocol.
Anyway good luck trying to adding your Evo to your provider! It won't be easy but it's do-able.
hmm okay you sound like a really smart guy!
so for the phone to wokr I need the esn number and what more?
if you could just list what I need in that type of thing, if you understand me right
and maybe how I could find those thing. like how can I find the esn number in the phone.. I google it. I saw that its illegal to change the esn number so therefor it really hard to find a way to see it. but since Iam not gonna change annything + my htc evo 4g isent locked to any operator I guess i can do what ever i want?
thank you for responding I find your answers very helpfull!
imei and imsi
now I found something interesting that I wonder if it will work
I have a htc hero with a si card in it. And there I can see the imei number.
the htc evo 4g has a IMSI number.. Both looks the samme to me couldn't I just change IMSI number on the htc evo 4g with the IMEI number That it shows in my htc hero?
and then ofcourse add the esn number to my operator network.. wouldint everything works just fine then?
Hi all -
I signed up for the t-mobile $30/month plan, but get spotty coverage. I want to try and see if the straight talk AT&T coverage is any better. If I get a micro-sim card from straight talk and put it in, and reboot the phone, would I be able to see my connection? Or would it be 'no service' until I've gone through the process of activating with straight talk?
I'm hoping it's the former as I'd like to know if my signal would be any better before going through the hassle of porting my number over. Thanks.

Thanks for the reply. Hopefully this is the case; I've ordered the SIM so I guess we'll see shortly!
I have Straight Talk (AT&T), you won't see any bars until you activate the SIM card. If you port your number, there may be a delay also.

Thanks! I was afraid that would be the case. I would want to port my number as well. I'll run over to my local AT&T store and see if they'll give me a micro-sim too; I figure if I get signal with that one, then I should be fine with straight talk on AT&T (unless that sim would have the same issue?)
Whatever may be the plan or carrier doesnt change a thing: You do not have any signal until the SIM is activated. The SIM isnt related to a network before it is activated.

I'm pretty sure that when I got my t-mobile sim card, I had bars showing prior to activation.
If it was, then your SIM card was pre-activated. This is the only explanation
As stated before, you will not get signal/bars until the SIM is activate. Period.

Odd, I wonder why they sent me an activated sim! I was still able to go online and put my IMEI, serial, etc in and activate it a few hours later.
Ah well, guess I'll have to activate service for a month to test with straight talk. I was just hoping to avoid the hassle of porting my number over prior to checking signal coverage.

I just switched out my plans from TMo Monthly 4G to Straight Talk AT&T. When I inserted the Straight Talk micro sim into the phone I got a message saying no sim card and had no bars until I activated it and had changed the APN numbers in the phones settings.

it must be only with this phone. because all my other unlocked phones have had bars showing no matter activated or not.
I think in some cases I've had bars / proper dBn showing in the settings in the past.

Then it should be easy enough to test as you'd just have to pull your sim card out and see if you had a signal. You could then look in the phones settings under network operators to see who's signal it is.

The original question was about a signal on an unactivated Straight Talk SIM card. I've had unactivated AT&T and T-Mobile SIM cards show a signal, but Straight Talk SIMs require activation to show a signal. I think it has something to do with them being a MVNO.

That would make a lot of sense! I'll post my findings when I pick up an at&t official sim card, and with the straight talk sim card.
Well, I have the straight talk sim, and sure enough - no signal at all. So that seems in line with what people here were saying. I visited two different AT&T stores as well to get an 'official' microsim, but neither place would give or even sell me a sim card. They said that I would not see signal without activation, and to not worry! That they could check coverage and tell me if I'd get signal! *rolls eyes* So that was a waste of time. I'll probably just bite the bullet and activate my next month on straight talk and see.
One question though - if I do NOT port my number right now, and instead get a new number via straight talk, would I then later be able to port my number or would I need to buy a new micro sim first?
You probably will be just fine, since you usually have a certain time to port your phone number. Even if you choose to port it right now, you will be given a temporary number during the procedure. But this is more of a question you should ask to the carrier, since it may be related to carrier policies or country laws. I have to admnit if i were you i'll be very careful to what they says
I have a SGH-I337 (AT&T) that I'm trying to get to work with a Verizon sim. I followed the steps in the post below.
http://forum.xda-developers.com/gal...aranteed-free-sim-unlock-mk2-nb1-nc1-t2852979
I follow the steps as stated but at the end the phone has no signal/loses signal using Verizon sim's.
Usually after a fresh boot, the phone will have bars but no data and cannot make calls. The phone states EMERGENCY CALLS ONLY at this point. After a few minutes the service bars will disappear and be replaced with a NO SERVICE indicator.
The phone no longer indicates an invalid sim, but does not auto load APN settings. Manually inputting the Verizon APN settings does not fix it either.
I have checked and it does NOT show the NULL IMEI on the *#06#. Also with the Verizon sim the hidden menus don't always function (*#0011# and such) although I've read that is an AT&T only thing, I'm not sure if that true.
When I insert an AT&T Sim it gets service/data immediately upon booting. I've also tried two different Verizon sim cards.
Thoughts or Suggestions? What am I missing?

I don't own any Verizon phones myself, so I could be totally wrong but:
- Verizon's SIM cards are just for data.
- Verizon uses CDMA (Your subscriber identity is in the ESN/IMEI)
- AT&T uses GSM (Your subscriber identity is in the SIM)
Both networks require you to authenticate yourself with your subscriber identity before they will give you data access.
Sounds like Verizon doesn't have your IMEI, so the phone fails to authenticate/connect.
Try calling Verizon, tell them you got a new phone, and you would like to tell them the IMEI of the new one, so that it can connect to data services.
Either that or they need the number off the Verizon SIM

It should be able to work with CDMA. I've seen the option in some of the menu's I've been through. And the guides have all said that they can work between AT&T and Verizon/T-Mobile or vice versa.
Also, AT&T will unlock the phone for you if you go to their website and fill out the stuff. The only reason I didn't do this is because I'm still under contract and I would have to break that and pay the early termination fee.
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.

Hi everyone.
I bought a V20 T-Mobile version H918 on eBay. Seller claims it's carrier unlocked. As a precaution, I bought a $10 Red Pocket prepaid SIM card to test it with (because my current phone is CDMA). First, I tested it with Red Pocket's "GSMA" sim card, which uses AT&T's network. When using this SIM, the phone mostly didn't work. Out of 30 tries, I was only able to make a phone call once. All other times, I got no dial tone. And I wasn't able to receive data at all. APN settings were correct, verified with Red Pocket customer service; also tried many other APNs I found on google, but they made no difference.
Next, after doing a factory reset, I tried Red Pocket's "GSMT" SIM card, which uses T-Mobile's network. When using this SIM, all services including calling, texting, mms, and data work perfectly. Although, despite it working, the phone is using the wrong APN (fast.t-mobile.com). This seems to be a hard default setting, and the phone doesn't allow me to select a different APN while this SIM card is inserted.
Red Pocket tells me that an unlocked phone should work fine with either the "GSMA" or the "GSMT" card. So, their advice, together with the fact that the phone isn't letting me change the APN when on T-Mobile's network, leads me to believe it might not be unlocked. How can I know for sure?
Note: IMEI registers as clean in the database. Also, the IMEI in settings, the one shown by dialing *#06#, and the one on the sticker all match.
Thanks!

If it was locked, I don't think it would have accepted the ATT sim at all. You can try playing around with the Device unlock app, but on the first screen it seems to pretty much always claim its locked for me
On my (pretty sure its unlocked, havn't stuck another sim in it almost since I got it months ago)
H918 that's running on a T-Mobile (proper, not mvno) sim I can freely add and switch between APNs
Keep in mind that the H918 isn't going to be good on ATT's network.

right, if it were locked, you wouldn't even get 1/30 phone calls to work, you'd get like invalid sim or something. Locked means it wouldn't even try to use the other sim.
Happend to find a video of someone with a simlocked h918 unlocking it, it shows networked locked where the carrier name goes.
