Problems with UM +423 SIM [split thread]
 

Hello

Sorry to bother you but I have an unblocked Iphone 3G (using turbo-SIM) and I m trying to use a united mobile Liechtenchtein SIM card. The network shows and I can sometimes receive messages but no incoming calls work and I cant send any SMS. Does anyone have any idea about this?

Thank you very much in advance

Don't put the same news everywhere, please

Have you credit?

Welcome to the forum, ag1540

I've split this to a new thread on its own and deleted other copies (and merged fedeprovenza's replies), as it wasn't really on topic on the threads you posted it

I've also moved two other replies from one thread to another

Hi

Sorry about that, i m new to these things. I do have credit but nothing seems to work...

Thanks

Do any other SIMs work in your iPhone? That's one obvious question.

If so, we know you're having a UM problem. If not, you're having a problem with your iPhone or with your unlocking device.

I have a similar trouble... actually UM+423 has italian roaming only on Vodafone network: well, ok but I can't receive incoming calls from all the italian networks! Vodafone, Wind, Tim and H3G has a busy tone calling any +423663 number... i can receive from Skype and stop.

Do you have a similar problem from french networks, I suspect :D

PS: i can send/receive SMS, i can call but i can't receive :chair:

Try turning off 3G. It's a turbo SIM issue as it sounds to me, nothing to do with the service providers nor the carriers.

I don't have that problem, I'm using it inside an old Siemens S55 :D

Anyway I think that simply a lot of italian carriers can't reach +423663 numbers... :chair:

Ok... thanks to snainom (http://www.prepaidgsm.net/forum/inte...-update-2.html) we can read that T-MO (USA) and T-Mobile UK have blocked Liechtenstein mobiles too :(

We can read it, but it's mistaken with respect to T-mobile UK. I've never heard this before and it reaches +423663 without problems at the moment
