So as the topic says, the g1 of my gf doesn't get EDGE.
Only 3G or, if only 2g networks are allowed, GPRS.
Now i want to ask why??
She has O2 and a Internet-flat on her O2 sim and has CM 4.2.5 on her phone.
It is like this since she put the SIM in.
Is it a phone issue? Or from the provider?
(I had to turn "send call id" to "on". It was on provider standart and she dont send a caller ID)
Should i try her sim in my G1 and try that out??
Hi,
I just unlocked my SIM card via a Verizon supplied code. I found an old AT&T SIM in my desk drawer - I called AT&T and confirmed the SIM is not active (nor has it ever been activated). I inserted it and the phone came up. However, if I use APN Manager, it shows I'm connected to Verizon. I'm able to make and receive calls.
I thought by inserting a different SIM I would be using that providers network instead of Verizons? Or do I need to manually change that somehow?
It's important I figure this out before my trip next month to Panama.
i think in usa the other network gsm bands are locked (so u wont be able to get service it wil just show no services i think) so even u insert them u wont be able to use that network ...
and u can change ur settings to gsm from mobile in network n settings i think..when u leave to panama or out of usa
hope it helps thnx

Is the phone sim unlocked? I don't know how it works with Sprint but that would be the case with GSM providers
If it's Sprint, it's CDMA.AT&T and T-Mobile are the only GSM providers in the US. However, it should work there if you get the SIM unlocked. The SIM unlock code is formulated based on the IMEI, so there are three ways to get it:
From Sprint. Probably the simplest, but tricky if you're not the phone's original owner.
Pay a site or unlocking service with the algorithm that decodes it from the IMEI. Usually runs around $10-$20.

You can also try this app, but it only works on rooted phones running the original ROM:

Good luck.

Bro, A CDMA PHONE CANNOT BE UNLOCKED. IT WON'T EVEN WORK ON ANOTHER CDMA CARRIER LIKE VERIZON. ONLY SPRINT SIMs WILL WORK.
Make sure u buy a GSM phone if u plan 2 use it on another carrier.
But the phone uses GSM! It picks up the network here but I just cant get the unlock box

Then it simply isn't a Sprint handset. CDMA phones can only work on that particular network. The phone is custom-made just for that network
