O2's Network Issues

Post Posted: Jul 12, 12 13:23

Guys,

After getting a tip off from Twitter I felt it best to make a post so you are all aware.

O2 seem to have altered the network requirements for connection and authentication of a users SIM card.

If you clone an O2/Tesco/Giff Gaff SIM card using a tool like XRY and insert this clone into an evidential phone (standard procedure for the majority) you might find the phone makes a full connection and is able to make and receive calls etc.

Just a heads up!

I'm guessing that you were able to connect to the network and make/receive calls with a cloned SIM card..?

Was it XRY you cloned with or something different..

A little more details would be interesting and helpful Smile

That is correct Adam, and yes, it was XRY in my tests.

We have tested 2 types of O2 SIM Cards both 2G and 3G with 2 different handsets - no signal or ability to speak to the network.

Hopefully that is a good sign that the network is getting back up to strength Smile

My tests were first thing this morning.
