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!!!

Tmobile Sensation SIM Unlock issue

It looks like there are issues with sim unlocking of Sensation, about half of the phones are not able to unlock.

care to elaborate? I just bought mine "unlocked" from a store, they entered in the unlock code in front of me, and my sim car was accepted. I entered in the APN settings at home, but I'm not able to connect.
I called HTC's hotline but they were pretty damn useless. "try restarting your phone. Try a factory reset." I tried both, but neither worked. What gives!?

I unlocked mine easily too. Can't get mms to work though.

Just call T-Mobile and say that your are traveling abroad and want to use local carriers. They will send you instructions and unlock code.

I have unlocked bootloader, installed recovery and rooted the device, still this crap pops up after inserting a different SIM card.
when bought seller claimed the phone was locked under Vodafone, but it is my understanding that Vodafone doesn't really blocked phones, besides I have unlocked the whole thing, if I install a custom ROM this would solve it all right?

***NEVERMIND i misread everything this is about some phone/sim lock code***
Hi there!
Put the Simcard in another phone and turn Sim-pinlock off.
I had this problem before when messing around phone's alternative OS
Hope this helps!

She tried all 00000000 (8 Zeros) but it didn't work, I'm starting to be concerned now as all the other measures haven't worked.
Even http://www.cellunlocker.net/htc-unlock.php
is reporting do not order if phone comes under Vodafone (Spain) which is the case.
I'm wondering if installing a custom ROM after a full reset could clear the issue!?

PUK Code
have you tried using a different sim card? As far as i can tell it looks like you have been locked out of that sim card. The only way to fix this is to get the PUK code from your service provider and enter it in. The default sim card code (the 4 digit one) is 1234 or 0000.

PUK as well as PIN is a combination of 4 numbers which she has.
She is being asked to enter the SIM Network Unlock PIN which is a combination of 8 numbers
As for a different SIM card she will try tomorrow.

if the phone is locked under vodafone then u need to get a unlock code from vodafone or buy a unlock code from some website(if ur trying to use it for another network). thats probably why u keep getting that message.

[HELP] Can't connect to any network in UK

Hello
I have problem with my Sensation.
I bought phone year ago (on polish equivalent of ebay), from someone who lives in UK and he send me it to Poland. It worked perfectly there, till now.
Two days ago I came to UK, and since I switched phone ON after getting off the plane, I can't connect to any of the cellular network.
I am sure that SIM slot is OK because phone asks me to enter SIM pin code.
When I am trying to manually select network I got 'Your SIM card does not allow a connection to this network', and when automatically 'Unable to connect to this network at this time. Please try again later.'
Wifi and GPS working fine.
I dont have a clue whats the reason of that, where the problem lies.
Phone has ARHD 6.7.2 ROM, firmware 3.33.401.106.
Any help is appreciated as I need phone badly, to have mail and internet access throught the day :crying:
PS. I am starting to think that UK seller could scam me, and sold me phone with blocked IMEI or something like this? :/

Hi have you tried to change your radio And ril? This could help you regain signal. I can't recommend a particular radio and ril because we live in different areas and it will be different. However you can start by experimenting with the generic ICS radios and rils and see of one of those will reconnect your signal.best wishes.Hope this helps solve your issue!

Sounds like your Polish carrier/SIM might not be allowing international roaming. Get a PAYG SIM for a couple of quid and try that. That'd prove the phone side of things.

Try
Try putting in a diffrent Sim card to see if it's that.

If your home network doesn't have an agreement with UK networks then your SIM won't work, not sure if this is realistic as I thought they were all only to happy to help others take money from us. Try a UK SIM, if that doesn't work then your IMEI is probably blocked in the UK, but not in Poland.

It's a simple answer Your phone has been reported as lost/stolen in UK and IMEI has been black listed. It's now paper weight in UK.
Pogon telefon w PL i kup sobie inny w UK.

Sorry for not mentioning - ofcourse I tried other sim cards, like o2 and vodafone - neither of it worked. My PL carrier sim worked in roaming in different phone.
So it looks like IMEI is blocked, I just wonder if I should go to the Police to check this out but I dont want to have it confiscated :/
Butif its true, Im not going to leave this scammer unpunished - I'll try legal action :/

Instead of legal action why not just find him and remove a thumd. maybe both thumbs to be sure.
The sad thing about having an IMEI number on the black list is that it can't come off that list. At least from my experiences.

Apart from it not being a paperweight. Revival is possible but ILLEGAL.

Phone wont register on network!! Need Help!!

Hello guys!
I love this phone, but i am having problems getting it to function properly here in Sweden. It was originally bought on a contract and simlocked to Tre (carrier). I bought the phone second hand from swedish ebay (much cheaper than brand new) with the intention of unlocking it and using with my carrier (Telenor).
Tre would not unlock the phone for me (have to see out 24 month contract) so i unlocked it myself using the services of unlockscope.com. The process was successful, and the phone no longer asks for a network unlock code when using previously locked sim.
The problems start now.. It just refuses to register on the network! If i switch the phone off, insert sim and start, then i get a brief flash of the carrier name in top left corner (2 seconds), and then it goes back to saying emergency calls only.
I cannot register manually, i have tried hundreds of times, even though the carrier appears in the list. The apn settings are also correct for my carrier.
I have also contacted my carrier and they dont understand the problem. I even had them run a check on the imei to see if it was blocked on their network (possible stolen phone) but it came back negative, no blocking whatsoever!
The weirdest thing is that it works when using my brothers Tele2 sim card! The phone registers in seconds and displays a nice 4g symbol next to the signal indicator! A thing to note is that this Tele2 nano sim fits very nicely in the tray and stays in place, whereas my telenor sim is extremely loose and falls out, though i have tried taping my sim in place with no success.
Can anybody relate to this problem or think of a possible cause? I dont know what to try anymore! I'm thinking that there must be something wrong with the phone, but then why does Tele2 work perfectly??!!
Sorry for the long post! I appreciate any help offered!

Hi
This is getting weird , did you try to do a factory reset from recovery also wipe cache and if that do not work you could also try to flash the firmware of the phone again ( odin)

I have already tried flashing with stock swedish firmware using odin (G930FXXU1APEQ_G930FVDS1APF1_VDS) but same problem persists.. One weird thing to note though is that even though i do a clean flash with unbranded swedish rom, the phone installs some carrier specific apps from the original carrier the phone was simlocked to upon first boot. How can that be??
Maybe its worth trying an international version?
Thanks for the suggestions

That is odd , yes try a totally different rom just to see how it turns out , even from another country it should not make any difference for the phone and connect easily to a network.

I will try with an international firmware and see if there is any difference.. if not i will follow that guide on efs partition in case that is corrupt.. This is so frustrating!!!
Is it at all possible that a very loose fitting sim could be the problem? As the simcard of the carrier that works fits very snugly in the sim tray.
