I have a Verizon TP2 and have unlocked the SIM. I'm heading for Ireland next week and have purchased a prepaid GSM SIM for use in Ireland. Do I need to reset any of the Phone Settings on my TP2 or will it automatically make the changes when I insert the SIM and turn it on in Ireland. Thanks.

i am using sprint TP2, easy switch to GSM network, just go to setting/connection management/phone setting/network
choose GSM ONLY, then system will search GSM network automatically
remember insert GSM SIM card in the phone first
You will have to get data connection setting for the prepaid provider if you want to use your data connection

That is what happend to me with my VZW TP2 in Greece.
Switching to GSM only worked for the phone but I need settings for SMS and Data.
Got the settings but VZW put some kind of lock on the connections settings app. My settings would always revert back to the vzw settings and I would always get connection failur pop up.
Got back home and found online some details about "CMGaurdian"
This program either locks the conection manager or imediately reverts changes back to stock. I think you may need to disable this in registry to enable data and out going sms reliably.
Hi,
I have a Nexus S I9023 with baseband I9023XXKI1
Provider is Telenet in Belgium, which is a full MVNO with its own MNC
When running any Gingerbread version, the phone works fine when going out of the country, and returning.
But with any ICS rom (stock or CyanogenMod) the phone will not be able to connect to any international providers, when my providers SIM is installed. But when I stick my providers SIM into another phone the SIM will switch over, after which I can put it back into my Nexus S and I can roam to any other international provider without problems, but the phone will not switch back to my own provider when I get back into the country. At this point I again have to put the Telenet SIM into another phone to force it out of roaming mode after which I can put it back into my Nexus S and it works again on my own provider.
I also tried with another Telenet SIM and had the exact same problem, so it is not a problem with the specific SIM itself. But when I stick in a non-Telenet SIM it does switch to roaming and non-roaming without problems. So it clearly is a combination of the ICS ROM with the Telenet SIM.
The only other thing I found is that the MNC code in apns-conf.xml is wrong for Telenet. It is listed as MNC=10 which used to be correct until sometime last year when everyone was issued a new SIM with MNC=05. But with a custom APN setup mobile data works fine.
If anyone has any idea how I could solve this issue, I would love to hear about it!
Cant Activate/Deactivate International Call Roaming on Nexus S.
Hi,
Same issue here, mine is Nexus S, running ICS 4.0.4, baseband version I9020XXKI1. I am not able to make calls in roaming. I spoke to my provider (O2 Germany) and they say that, I have to deactivate the lock (Lock to activate roaming). I haven't found any way to unlock this service. I have not tried what the OP has mentioned in his post (i.e., to put the sim into another phone and then try back in Nexus S). But I would like to know, how can I Activate or Deactivate the roaming lock ??
Thanks,
Cheers!!

The only roaming feature you can enable is for Data. This has no effect on roaming for normal phone usage.
You can change this setting under "System Settings" -> "More..." (under Wireless & Networks) -> "Mobile Networks"
Here you will find a "Data roaming" option, and possibly a "National data roaming" option
I have a Desire Z with Android 4.0.4 and Telenet for the cellphone also. I noticed I have to activate the romaing in Belgium to have the data connection which is strange as I'm in Belgium. Now I hear that they can be issues calling/sending sms abroad... I'll see when I'll be in Croatia.
I activated for the moment all the option (data roaming, national roaming) for the moment, nothing more strange than having the romaing activated and the 'R' in the network signal.
National Roaming seems to be needed on some phones, since the Telenet SIM swap last year to get a data connection in Belgium. On my own Nexus S phone I don't have the problem. But on my wife's SE Xperia Mini Pro (2011 model) with stock Android 2.3.4 it does have this issue.
The old sim used MNC=10, while the new SIM uses MNC=05 and it seems that some phones have some kind of issue with that.
MNC is the Mobile Network Code, which together with the MCC (Mobile Country Code) forms a identifier per provider.
http://en.wikipedia.org/wiki/Mobile_Network_Code
I narrowed down the issue somewhat.
Basically my prior workaround that the SIM needed to be swapped to another phone to force the network to connect was false.
What actually needs to happen to force the phone to enter or exit roaming is to pull the battery.
Rebooting the phone, or shutting it down and rebooting (cold boot) does not make a difference, the battery needs to be pulled and then the phone will switch networks.
I found this by accident, because I was out of the country and it was as normal refusing to switch to roaming mode. Then the battery died and I connected power to the phone and booted it, and it suddenly connected to a foreign provider in roaming mode.
Getting back to Belgium, it again refused to switch back, so I verified it by just pulling out the battery and putting it back and the phone successfully was able to connect to Telenet again.
In other words, some component needs to be reset for it to successfully switch to roaming and back. This component does not get turned off when the phone is turned off, so the battery needs to be pulled.
I recently switched from my GS2 (AT&T) to an unlocked GS3 (Verizon), but I couldn't find an APN listing to match my service so I used HiAPN to backup the settings from the old phone and used the same app to apply them to the GS3. It is now not allowing me to make or recieve phone calls, or even access the 4G network on AT&T. It says I'm trying to make international phone calls when I dial out, when I answer calls no one can hear me, but I can still text. I have the phone set to GLOBAL, should I set it to GSM?
1st thing to do is set it to Global mode! 2nd if you google AT&T apn you will find one around that you can add and 3rd you should not save a received call(Edit it to put the 1 after the plus sign) or call back after receiving a call as it doesnt input the number 1 after + so it makes it +(zip code)
And this phone only gets EDGE on AT&T
Trying to switch from CDMA to GSM, sprint to tmobile and tried 2 ways that haven't worked. 1st way involved selecting preferred network to global ,swapping out SIM cards ,selecting APN . The 2nd way was dialing *#*#72786#*#*, swapping SIM cards, while phone is restarting select APN, restart.
Our phone came with a free 1 yr service from FreedomPop. I'm suppose to be able to cancel service at any time.
I also took the phone to a wireless repair store and they told me the phone can't be switched to GSM. I've read that it can. HELP!!!
The main problem is that the phone can't send texts or call out. It can receive calls and texts.
The free calling and texting app Textnow which formerly only worked on Wifi or with a paid subscription is now offering Free cellular service through the Sprint network. You just pay once for a $9.99 SIM activation kit and never need to pay a monthly fee or anything again. The Free part is only Voice and text. Their voice and texting does use mobile data but mobile data can't be used for anything else like surfing the Internet unless you pay extra. It does of course have ads to pay for this service but I haven't found them any problem. You have your own phone number and it automatically will switch between available Wifi and cellular for calls and texting. Great idea in my opinion for an extra phone number or backup phone or even a primary phone if you are in a good Sprint network area. Your phone must be compatible with Sprint's network (CDMA) or you can buy refurbished phones from Textnow that are all set to go.
Textnow now has a GSM SIM that works through T-Mobile. It took a bit of digging to find info needed to make the SIM work but so far I can only make outgoing calls and texts when on cellular (VoLTE) with
Wifi turned OFF. I can't receive calls or texts unless Wifi is ON. Is anyone else trying their new GSM SIM and had this problem? This is free cellular! You just have to put up with some ads. Textnow states you can make and receive calls on cellular but so far can't get the incoming working.
If you have trouble with this new GSM SIM even connecting here is the solution I found to at least make outgoing calls work: Go into settings > Wifi and Internet > SIM and network settings > SIM (T-Mobile) > Access Point Names > Add APN. Getting there may vary some by phone and OS version but you need to add the APN - Name : TextNow APN: textnow.static - then just save it and after saving choose it as the APN in the little circle. Turn on Airplane mode for about 10 seconds and then turn back off and you should see VoLTE and be able to make calls. If you can receive calls and text also please post here with anything you did to accomplish that.
