Issue with SIM card activation

[NorthJ1]

I got a new phone (iPhone 14) from EE this week. It arrived along with a new SIM card to activate so that I could keep my old number. I activated the sim on Saturday as per the instructions and it said it could take up to 24 hours. 
But it’s been almost 48 hours and my new phone/sim still hasn’t connected to the EE network.  My old sim in my old iPhone 11 seems to still be connected to EE but it cannot make calls or texts so clearly is in the process of doing something. I can’t call 150 or any other EE number on either phone for help because it won’t connect. Please can someone help me get my phone connected to the network?

If you were just changing your phone whilst keeping your existing EE number, the usual process is just to take your working SIM from your old phone and put it in your new phone. There's certainly no need to unnecessarily replace a perfectly working SIM unless there's a fault with it.

If your existing SIM is working in your old phone, then as per Apple SIM sizes both the iPhone 11 & iPhone 14 use a Nano SIM - can you put it into your new phone, and does it work?

Yeah I thought that was usual process but because EE had sent me the new phone with a new sim for a phone upgrade which included instructions for activating the sim, I thought that’s what I had to do with this new SIM card. I’ve tried putting the old SIM card in my new phone and it shows that it’s connected to the EE network but doesn’t receive texts or let me make calls on it so I assume the process of activating the new card has disabled the old one somehow.

@NorthJ1 , you would need to ring customer service, either via another phone or using something like Skype for free:

08000798586

They should be able to sort this out for you, or if you are near an EE high street store, they should be able to help also.
