Will a T-mobile PAYG fone, work with a T-mobile contract SIM..........

numper

HI, MY T-mobile contract fone needs replacing.........

Does anyone know if I purchase a PAYG T-mobile fone, if my SIM will work with it?

Also will Vodafone contract SIMS work in Vodafone PAYG handsets?

Thanks in advance

Just because they're the same network DOESN'T mean they will work. Most providers nowadays use "SP-Lock"s, meaning the phone is locked a specific network code. However, some networks use different network codes for PAYG, contract, etc. So sometimes the phone won't recognize a contract SIM, if it's locked on the PAYG code. This is all just theory though.

I successfully done this with T-Mobile. Never used Vodafone though so can't comment

In a word, YES It's the network that it's locked to, not the SIM.

Also, a virgin SIM should work in a T-Mobile locked handset, as should a tesco SIM in a O2 locked phone..

Virgin Sims wont work in a TMobile locked handset and Tesco's will not work in an 02 Locked Handset. They use different locking codes even though they share the network.

A TMobile contract sim will work in a TMobile PAYG phone, but as Senab has said, with Voda they sometimes use different locks for PAYg to contract.

my tescos/o2 are interchangeable, as was virgin/t-mob, both older less sophisticated phones (nokia 3310, 3410 era) though, so maybe that's been the difference ???

Virgin sim works on T-mobile PAYG phone, but not the other way around in my case. Then my T-mobile phone is old, so may be different nowadays...

my tmobile locked k810i and k700i both accept tmob/virgin sims, but my virgin locked k750i will only take virgin sims as its locked on SP and network. my k810i is locked on the extended lock
