Cutting it short:
Got the Touch Pro for free from Hong Kong, brand new. Sim unlock (as indicated on HTC distributor website w/ IMEI and S/N confirmation).
Flashed to ROM version: 5.07.832.3 Radio version: 1.11.25.01, all from HTC website.
Using the phone in Canada, service provider is Cityfone (the phone indicates Rogers Wireless). I don't have a 3G plan so I'm using regular GSM network.
Problem: Everything on the phone works EXCEPT the phone function itself. Everytime I make a call or receive a call I can only talk for 5 seconds, then the phone mutes automatically.
Tried setting to GSM only and shutting down HSDPA, it just doesn't help at all.
Can anyone identify the problem for me? I really have no clue since I'm new to this pocket pc tech. If HK 3G phone simply doesn't support GSM network in Canada then I don't even do anything with it. If it's just hardware problem then I'd just send it back to HK for replacement.
Any input? Help please...Bump
I will tell you it definitely supports the GSM network in Canada but not the 3G network. I don't know the problem though.

Hmmm, the previous poster is correct, Rogers is the only GSM provider here in Canada. And they do support 3G and H data connections, but you need a North American version (e.g. the FUZE) to use the H speeds) It should be fine for voice, tho. I've never heard of Cityfone, but it may be a subdivision of Rogers or leasing the line time.
Where did you get the SIM card for your phone? It sounds like Rogers is not recognizing the card and is cutting you off.
I know for a fact that unlocked Raphael's will work fine on Rogers, since that's what I'm using, and I've used a lot of other GSM phones on the Rogers network with no problems at all.
If you really want to keep the phone, I would suggest checking with Cityfone re: whose network are they using, or set up a Rogers Wireless account.

I've been using the same sim card for a very long time without problem, on celphones that were purchased locally or other tri-band GSM phones in Hong Kong. I swap the sim card back to my Sony Ericsson W800i and the voice call is fine.
I used my mom's sim card (from Rogers Wireless) and same problem occurs on the Touch Pro--5 secs and the call mutes.
I'm just not sure if it is hardware problem on the Touch Pro or if there is compatability issue with the network (which I doubt since I can talk for 5 secs before the phone mutes...). Any possible way to identify what the real problem is?
Hello everyone,
I just purchased a Motorola Photon (my first android and smartphone) and was wondering if someone can help me answer my question.
I would like to use the Photon with a SIM card during my overseas travel and wanted to know if unlocking the bootloader will allow this? I know I can't use Sprint's Worldphones while overseas with SIM cards from other countries - I had my friend confirm it from his BB-Bold. According to him, even if he switches to GSM, the phone automatically goes back to CDMA and uses Sprint's international Voice/Data.
I, however, wanted to know if unlocking will avoid this behavior on Photon? I really love this phone and would like to use it even when I am overseas.
Please advise.
Thank you in advance!
Photon 4G Sim Card
I bought a Photon 4G on Sunday, I just went to Mexico on Monday and tested a sim card from a local carrier and it worked. Just had to switch Network Mode to Any GSM/UMTS mode.
Hi,
Recently got a Koodo GTi9020A and have tried to use it in the UK with a 3 Sim.
The phone gets a full 3G signal, data and internet work, however there is a problem with making calls when using the 3G signal.
When the phone is turned on I can make one call to a landline, however if I hang up and dial again there is silence. Calls to other mobiles are scrambled.
I have spoken to Google and have been told that the Canadian software will not work with a UK Sim and the phone will need flashed with UK software.
The phone is therefore 'locked' to the Canadian networks. The lady from Google mentioned that a fully unlocked phone would be more expensive!
Any advice appreciated.
Thanks.
I recently bought an unlocked Google Nexus S from amazon. The Device works fine on ATT network. When I got it to India and tried inserting an Airtel SIM in it. The phone shows complete Signal strength but says emergency calls only. On the lock screen it says insert SIM.
When I search for available mobile networks it shows my network but unable to connect to it. It does not even ask for unlock code when I insert a SIM from another carrier.
Is this because the phone is locked or is there some other problem?

What network frequencies does Airtel use? If non of them match that could be why, oh and Nexus phones are never network locked
Sent from my ice cream powered Nexus S
Yeah, frequencies should be the reason here.
But only for 3g, the us always being special, especially at&t. ^^ 2g should work worldwide. Set it to "2g only" and see... (if it works, slow data, but at least you can make calls)
I got a Samsung captivate from ATT and it worked also my Galaxy S 4G. All these are quad. band phones so, they work worldwide. Could be some other problem. Got a good deal, so dont want to return it, but I guess I have no option now.
Tried a new sim?
im gonna be going to india in a month or so and i wanted to know if the i9020a will atleast work with voice in india. airtell or vodafone it doesnt matter. I don't need 3g but i was hoping voice would work so i could just use this phone in india.
did you try to reset the phone?
Hi All,
I bought a Tmobile galaxy s blaze 4g (SGH-T769) from HSN last year, it was never activated or used on tmobile. I tried to put a old at&t sim I had in it and it said sim invalid. I get the same message when I put an active Verizon sim in as well.
I used a service online for an unlock code and after following the directions it prompted for pin and it seems to be unlock after entering pin
When I insert the Verizon sim it does not display invalid but it cycles between Verizon APN and Vodaphone NL .
When I try to make a call it said not registered on network
When I put the at&t sim back into the phone, I get the not registered network but am thinking because its an old inactive sim or not?
My issue is I want to use this phone in Brazil this summer so I need it unlocked and right now I am not sure if it really is unlocked?
any ideas?

Just so I get this correctly, Verizon, even though it has a sim, is CDMA network Only. So my my only option to test is a vlid AT&T sim?
Thanks for responding
update
I used a friends at&t working sim and it worked great so the phone is unlocked. I guess the Verizon 4g lte is different frequency anyway plus for some reason I thought it was some form of GSM. lol
ALL good to go here..
thanks
