Hi, I have a new Nokia 6070 which is blocked to Tesco Mobile network, United Kingdom. I tried twice unblocking code generated on one site offering free unlock, but it failed both times. THe codes were the ones following: #pw+181914305076453+1# #pw+282015205147755+7# I am worried about blocking my telephone for good. At the same time I would appreciate if I could use my telephone with my foreign sim card. Any idea? once more: Tesco Mobile United Kingdom 353628015797351
