No network in US but works fine in Canada

Hi guys,
I'm new to the forum. I've tried searching for some answers but can't seem to find how to resolve the problem. I'm quite new to using PPCs so let me know if there's any information that you guys need.
So my phone works fine in Canada using Rogers... but everytime I go to US, I cannot detect a network for my phone and there's a "!" at the top. I tried searching for a network and it says "no network found" or sometimes it tries to register and then it fails in the end. In US, my phone automatically shuts off... I have no idea how this happens but everytime I go to look at my phone after leaving Canada, it's off. So when I go to turn it back on, there's no phone signal. I have no idea what to do as I'm not very familiar with PPCs.
Thanks for the help!

Which phone are you trying to use? Guessing Touch Pro?
Is international roaming or data roaming added to your account with Rogers?

Hey I have the HTC Touch Pro... yeah I've used this sim with my eten m700 before and it works fine. It just always seem to be searching for a network then it can't find any.
Thanks!!!

are you a prepaid customer? if so, Rogers doesnt allow roaming outside of canada.

Hey there... Just figured I'd pipe in here...
I am still using a TyTN (shopping for a Touch Pro today), and although I was able to always use my phone in the states, since my last firmware upgrade (WM6.1, new radio stack)....
....I can't get any service when I cross the border.
SOMETIMES I'll get 10 minutes of service over the course of an entire day. Very strange.
It is obviously firmware-related... Good luck with your phone...!

Thanks for all the help guys...
Nope I'm not a prepaid customer... should I be upgrading something on my phone to see if it works? Sorry... really don't know much about PPCs here!

just out of curiousty, have you called Rogers to ask for an updated OTA to be pushed to your SIM?

I've contacted Rogers and they said it has nothing to do with them... it's my phone! Should I contact them for the OTA? I'm sorry to be so noobie but... what does OTA do?
Thanks again!

Anyone help please!!!

[Q] Pattern unlock on android

Hello people,
Sorry my first post being a question and also the fact that this particular issue I am about to address is previously being discussed in this forum., but I have tried my best to resolve the issue before posting it here. Its been a week now, my phone (samsung fascinate i500) is locked due to too many pattern attempts. It is registered to Reliance (carrier) now, originally it was verizon. data was still not enabled so google account was not set, so cannot login using that too. have been searching for solution since a week now but the issue is still not resolved.
Phone details: carrier - reliance, non rooted, android version - 2.1, update 1, USB debugging - off (cannot enable now as it is locked) so cannot perform ABD, tried updating OS but unable to as the phone is not rooted. Tried factory restore also (5 times), not working. Visited local samsung service center , but the guys said they cannot help as this is a foreign handset. tried one click unlocker also. Please help. Is is getting very frustrating now.
Just want to ensure you people that this not a stolen phone, I bought it through ebay and I have the receipts.
totally at the mercy of this forum now.

Amazing to see that among almost 48 lakh registered members no one even bothered to reply. What a great forum,..BTW,.. my problem is solved,.. a local guy who didnt even knew that my phone was cdma cracked it. XDA developers ha??????? what exactly do u develop?? braindeads???

[Q] How do I add APNs on Verizon Galaxy S3 running 4.1.1?

I have a Verizon Galaxy S3 (SCH-I535) running Android 4.1.1. I was told by Verizon prior to moving to England that, with this version of Android which unlocked the "world phone" capabilities (GSM), that I would be able to use my phone abroad with a new sim on a local network.
Fast forward a few weeks, and I am in England with an Orange sim in my phone. I have no problems with voice, but I cannot access any data services (I have no trouble receiving texts, but cannot send them - I think this is a problem with the sim though). After searching around the internet for a while, it seems that the solution to my problem would be to add the Orange APN settings to my phone.
HOWEVER, Verizon's version of 4.1.1 does not allow you to edit APN settings! When you go to the APN menu, there is nothing displayed and the only settings option is to Reset to Default.
The closest thing I've found to a solution is here, but it's a bit out of date as the method isn't for 4.1.1. I'm a bit wary of rooting my phone and installing a rom, as I've never done anything like that before.
Does anyone have any experience with this sort of thing that might be able to offer a solution? I would be willing to root my phone if necessary, but I'd need to be directed to a pretty explicit noob guide for doing that :silly:
Thanks!

Getting root is easy with the toolkit linked. Should you have any questions you can read the thread or search galaxy s3 toolkit on YouTube. Just keep in mind some videos are outdated and that you have a Verizon cdma galaxy S3 running 4.1.1.

Search this same thread and the APN fixes are here. There is also an APN fix in Note 2 forum that should work. Once you change APN should be good to go with Orange. Say hi to my Uncle in Birmingham. He on Orange also. Cheers. :laugh:

What ended up being your solution?
I'm going to Italy tomorrow with a Verizon S3 and APN settings are locked. The phone is rooted and I would love to be able to use a local SIM on data!
Thanks in advance.

No solution yet. I'm going to look at the link above when I can get some time to sit down and focus on it. Hopefully it fixes it.
BTW, although it's billed as a CDMA phone, it is able to operate on GSM as well. That's the whole "world phone" thing that Verizon has been talking about.

I understand it's a world phone, but I wanted to drop that in because I wasn't sure if the Toolkit states "CDMA" under the device selection screen. I know the Galaxy Nexus or Razr Toolkit specifically stated CDMA. I just didn't want you to accidentally pick the wrong one. After looking at screen shots of the Toolkit you shouldn't have a problem it doesn't mention CDMA only Verizon is stated.

Unable to add APN.

Hey there,
Sorry for going there, but I have not been able to find a fix for adding in the APN on a Verizon Samsung Galaxy S III. I have it on Cincinnati Bell at the moment, and have it rooted. I have voice and text, but not data. I have used the APN Manager Pro to see the APN that I need to use, but for some reason it will not use it or be able to edit it? Any thoughts?

Yes.
Get titanium backup pro and make apn mgr pro a system app.
You should be good after that.
This is confirmed working on Vodafone Italy and ill post results from China and hk in about a month

And please spread the word on this.
Spiting Verizon is my new favorite hobby.

I have a very similar problem. I have a Samsung S3, not rooted, but unlocked from Verizon. I have been in Kandahar for a month or so. My SGS3 with a local provider will make and receive calls great when coverage is there. My problem is, I can only seem to text local here not back to the US, or get email and no Google Talk. I went to the shop where I got my card here, they told me that Verizon needed to unlock my phone. I know it is unlocked but I made the call home, Verizon told me what I already knew. I went back into the store, once again, next they said Verizon needed to unlock my APN? I called again, finally I got a response from Verizon saying that Samsung needs to release the patch so Verizon can unlock it. If anyone knows of such a APN patch I would greatly appreciate it. My lap top screen got cracked during a patrol so doing all of this and email is quite the B!tch! I have always had success with this forum and hope it will continue. Once I send my lap top back home to be warrantied, I will not have any way of getting the usual business done for at least a month. I'm trying to hold off on the lap top until I can get my phone fully functional. I do not have internet connection on my phone, just my computer, I guess that is the APN, that is still locked. I could do all of this if I had WiFi, but it is not allowed here by the company that provides internet. They do have WiFi in some areas, but it is always bogged down with everyone else trying to use it. Also, I am not too sure if I want to attempt to do a root, the internet service here is very slow. Thanks for your help. Please remember, I am atleast 8 1/2 hours ahead of you, so response time will be delayed.

[Q] OPO on T-Mobile - 2nd OPO, same problem - network connection issue

Hello all,
Back again.
I'm trying to get my "2nd" OPO to work on T-Mobile USA.
First of all, it is not a SIM issue. I have 2 microSIMs that can be used freely across all T-Mobile enabled devices.
Once I try to connect to T-Mobile, it gives me a "Your SIM card doesn't allow connection to this network".
I tried the 'unlock the basebands/LTE process', got as far as ADB talk, but I cannot execute the su command, so the setprop does not work.
And this is my 2nd phone, a replacement from OPO. 2nd month running already. The 1st one had the same issue, but at the time I did not do research on tinkering with it,
and was 'NAIVELY' believing in OPO's customer 'service'.
Took me 2 weeks just to get 2 basic replies of "tech support", which didn't help since they gave me rather weak tech suggestions - 1st suggestion was reset, 2nd suggestion
was to look at the T-Mobile thread (I cannot connect to network, so how do you expect me to connect to APN?!?) . Then took them 3 weeks to go through the RMA process,
and yet another 2 weeks to send me a replacement(not).
Any assistance appreciated.

Check your imei on the tmo compatibility site. It could be blocked. Dumber things have happened. Double check that the SIM is installed properly. Second replacement and multiple sims seems to point at something you are doing.

Thank you for your response!
Yes, the IMEI is not recognized on t-mobile. Which is stupid since this is the second one (the 1st one had the same issue too).
Has anyone else gone through this frustrating experience? To have two OPOs whose IMEIs are not recognized is...... well.... $!%#!. :silly:
SIM installations are fine. I have done them multiple times, with the same results.

Future reference no need to create a new thread to ask the same question as before. You should of just continued your first thread so others would know what you have been going through and what was done to try and fix it. Glad you got it sorted or did you....

Got it.
Unfortunately no. Second OPO, same issues again. IMEI is not supported either. So, Groundhog Day here.

I'm with you man. I left vzw for T-Mobile and struggled like hell with getting the OPO working properly on it. From loaner phones to multiple sims, they/we tried everything. End result was to leave for at& . The signal is strong, but yet I keep missing calls daily. This beauty is going up on eBay. I just can't take it anymore. Sucks because Dev involvement is Huge here

Register and activate your phone with T-Mobile... I had the same issues for MetroPCS, and that fixed it.

I dont have any issues with network on Tmo, but what do u mean by register and activate ?

What I am saying is, you need to contact your carrier and get your IMEI entered into their system in order for the phone to run all services correctly on your carrier... whether it be T-Mobile or anybody else.
My 1+1 ran most of the services and operated on my SIM card and phone number in my hometown area. But, when I went to another area or town, it would not register with or run on any carrier... NONE! not even roaming like it does at home. I had to go to MetroPCS (on T-Mo network) and get my phone activated onto their system for it to run data, and 4G LTE. By just inserting the SIM card does not automatically sign your phone into the system and you should call or go to a dealer store and get it turned onto your particular carrier to run the network correctly.
Hope this clarifies my statement.

I never had to register or the like with my OPO for t-mobile. Didn't have to with my wife's OPO either.

It's a common enough issue across carriers. Sometime you do have to register the phone, and make sure you have the correct APN settings.
I just gave my daughter my OPO, I had Consumer Cellular (ATT) SIM in it. She dropped in her T-Mobile SIM and off she went, working perfectly. She's been using the phone about 2 weeks now, and in response to your question, I just checked her aPN, since I knew it's been working perfectly for her, only to discover the phone pulled in a MetroPCS APN! It's been working so well, she doesn't want me to change it to the T-Mobile APNs that are in the list.
Here is her APN settings (Calif-San Diego area), MetroPCS
name MetroPCS LTE
apn fast.metropcs.com
MMSC http://metorpcs.mmsmvno.com/mms/wapenc
mcc 310
mnc 260
apn type default,mms,supl
apn protocol IPV4
apn roaming protocol IPV4
mvno type none

What APN is you OPO set to?

I had just popped in the SIM card and it did work in my local area. But when I went outta town, my phone wouldn't connect to any services, no roaming either. I use MetroPCS on T-Mobile network, and nothing would run without activation on their system and registering the IMEI. So, results may vary depending on the carrier or area.

registering
I am a frequent visitor to the USA from Canada. Usually with my original Samsung or Nexus rdware from Canadian carriers, but unlocked.
Each US carrier has insisted on registering my IMEI prior to activating a SIM. It seems to the user you can pull a SIM and place in any old device and most times, no problem. But that's not the carrier approved method.
T-MO was very insistent on this. To the point they would not activate a SIM for me with out the device and the IMEI first
Hopefully registering with your carrier solves this. It's a thing and may be the point of issue for you.

Help! Tmobile Samsung S7 locked only on 1800 mhz band. Already rooted

Hi everyone.
Last time i was in xda forums was when i try to mod my windows mobile CE 5.0 lol
This is my sad story:
I bought in the US a samsung s7 with T-Mobile SM-G930T, i paid a guy who 'unlocked' it in there. After that i brought it to Colombia, in here i run the T-mobile unlock app which succeeded and erased itself after that. Then the cellphone started working with all the mobile companies in my country except for one that operates over 1800 mhz, other companies do work fine. When i insert a simcard of this company it just says that 'Not registered in network' and wont do nothing. I already tried to put the APN settings correctly (Actually it automatically loaded every company settings detected).
After that i tried to root with a modded Odin with a custom ROM and it succeeded and i got the SuperSU application, tho the cellphone its a little laggy now, but neither that way it worked. Anyone knows how where should i start looking?
I went to this company support and they sent me to Samsung support, which redirected me back to this company, lol
Thanks in advance guys
Update:
I have entered the service mode and enabled just the bands i need, also all the bands both in GSM and LTE but could not get it working
Also i tried to find the HiddenMenu file on /efs/carrier but its just not there.
