[Q] International Use: "No GSM/UTMS networks were found" - Motorola Photon 4G

Hi Friends:
I bought used MoPho 4g to use overseas (stock 2.3.5 rooted). I popped in a VN sim but the phone tells me that no GSM/UTMS networks were found.
I switch to Global mode, but that still does not make the GSM detected.
The foreign sim works on another unlocked feature phone, so I know the account/SIM is good. When I go to the security settings to do a SIM lock (just to see), it says that no SIM is found.
In any case, I would think even if no SIM is found, that the phone should detect a GSM network, but it does not.
Thoughts?

You could have switched baseband. Try to reflash radio with RSD Lite. But first read, before flashing. Read twice or more.
Start in Photon Compendium thread and then 2.3.5 sv2 custom sbf thread.

Before playing with ROM flashing, confirm you have correct network mode:
Settings -> Wireless & Networks -> Mobile Networks -> Network Mode. Try choosing Any GSM/UMTS network and wait a couple of minutes. You may also try to choose Automatic.

I use it for gsm in the US and find that it sees the network better if I set it to automatic.

Yes, I set the network settings to both GSM and automatic. Both cannot detect the GSM network.
It looks like there are no other options, so I will look into flashing the baseband again.

have you checked that block roaming options aren't checked? happened to me a couple times. when you switch to GSM/UMTS mode, roaming block (block calls, data and sms) options activate by default.

---

Roaming guards are unchecked. Still can't get a gsm signal.
Thanks.

If you are (still) using Sprint, you need to call their international team to enable international roaming/usage (even if you are not using Sprint SIM).
This happened to me when I went to Germany. I had to call them from there (via VOIP) and I was able to use Simyo prepaid.

Hi Axelfox,
Were your questions answered and are you able to get on a GSM network yet? You can PM me if you like, I am currently in VN and using MobiFone SIM card with their unlimited 3G for $3/mo. Which SIM are you using?
Try this, go to the Google Play market and download an APN manager such as:
Offline SIM APN Database
Tweakker APN Internet MMS
APN Manager Pro
-GP

Thanks to all. I was not able to call Sprint to activate international roaming, but that is good to know. It was my understanding that it was internationally unlocked out of the box and I could just pop in the sim.
