FINALLY! GSM on DROID 4!!! IT WORKS!

[Germanguy]

got gsm patches on my rom links work someone on xda tried em

Where are your ROM links, please?
I am confused, actually. Is there a different GSM patch other than the one listed in the OP of this thread? Because ICS leaks for the D4 enable global mode by default using the same 8 byte string in RF_BC_CONFIG_I as the patch listed in the OP.

Just to be clear, this just unlocks the GSM bands, right? It doesn't mess with the CDMA or LTE radios, right? (I can still use it on Verizon)


Still no dice.
Let me just run through all of the settings to make sure I have them correct:
-MA: MDM 6x00
-USB: PST USB Driver
-NV Access: 1877

The drivers are installed, I am also running the program in comparability mode for Windows XP.

I set my phone to camera mode, w/ USB debugging on.

If all of those things are correct, how come I keep getting a no device dectected error? (The box in the upper right hand corner is red).

If you are on ICS, there is no need to do the Radiocomm patch. GSM abroad bands are enabled out of the box.

I was thinking for domestic US usage. Does this method not work for that?

Nope. Myfishbear has a GSM patch listed in his eclipse ROM thread. It is from Olegfusion and contains prop file edits as well as a different apn config file for overseas. Might give that one a try. Have not tried it myself.

ok Going to London next week.

Just to confirm. I land in london, walk into a Vodaphone or the like and buy a sim card. Am I buying a pre-paid sim card? I'll be there for about 3 weeks.

Never done this before and wondering what it'll be like. I assume, with the new sim card in, I'll have a local number? Until I reinstall my current Verizon number.

Thanks gang.

Assuming GSM is active, yes. It is the same as getting a prepaid SIM here. You will have a local number and when you return to the US, just remove the SIM card and Verizon should work again.

Anyone else getting the following message on their phones with a foreign GSM SIM card and the ICS leak?

"This SIM card is from an unknown source"

The GSM voice functionality still seems to work fine (haven't tried data yet), so the message seems harmless. But it'd be nice to get rid of it.

Phone working great with vodafone UK sim in uk and france. A few observations:

1) needed to get the APN info before data would work with vodafone UK because it didn't know it.
2) GB works fine with the hacks to make it work. Didnt want to mess with ICS as it was still too preliminary when i had to make the decision.
3) cannot find a number format that works universally: 01144 doesnt work with a vodafone sim card, 0 only works in the UK, +44 doesnt work in the UK and messes with google voice (until you disable it) in france. Hopefully this functionality is improved with ICS as it is a step backwards relative to blackberry.
4) poor reception in rural areas with GSM. Might be a strict roaming policy.

Now Verizon has released ICS, anyone tried to get it working with international GSM, not rooted?

Yes. I'm posting this now from my Droid 4 ICS in Asia, on a GSM network.

all you have to do is enter APN settings manually.
