I know it's been possible (well, it used to be) to stick a Virgin Mobile Sim in a T-Mobile handset and get it to work without an unlock.

Is the same possible with O2 handsets & Tesco Mobile?

Also, with O2's 'X' range of handsets, can you enter new MMS & GPRS settings, say, if you went to another network?

Just to let you all know, I went and tried a Tesco mobile in some O2 handsets with the help of the local O2 shop and found that it worked in the handful I tried. With the rates that Tesco give you and at only £4.97 for a SIM you can't go wrong!

I just hooked up 3 low-user family members to Tesco Mobile this weekend, one on a Brand New 02 Sagem MYC5-2 I'd easily setup up for Tecso - no need for unlocking or anything!

10p per minute Cross Network calls & 5p Cross Network texts for your 3 favourite numbers or 20p & 10p cross network the rest of the time, 25p MMS plus free GPRS till the end of Feburary? Barg!

iv got a sagem myx7 and tesco sims work in it fine.

Tesco mobile uses the o2 network, thats why you dont have to unlock ur phones and also virgin uses the T-Mobile network
