Phone Texting out with incorrect number
I switched my phone from 3 to I'd mobile. After a few days I switched my new number to old number. However when I text people it comes up with thr old I'd mobile number, if you try and call it you can't get through.
As i use my phone for work this is causing confusion people asking who it is.
I have tried resetting the network settings, taking the chip out of the phone but this still happens.
Can you advise why this is happening.
