No mobile network

[Smcleod]

I phoned last Monday the 15th April as I recently received a new phone for my Birthday and the problem I'm having is that my 4g does not kick in when I am out of the house, only wifi I get is from connecting to house broadband. I was sent a report no CIT-A057156. Up to tonight nothing has been resolved. Please help

It's a commonly reported problem which is only fixed by asking O2 to complete a network reset of your account.

This is achieved by disconnecting and reconnecting you.
