Hi, Thanks for all your help. I'll try another sim later, just think it's strange cause I get my contacts so the sim must work from that point. Anyway thanks again
I presume that your contacts are backed up to Google and not stored on the SIM which might explain why you can get them even if the SIM is not working?
I think my old sim was a nano and I should be using a micro so I have requested to change my sim. Hopefully that should do the trick. Thanks
If your SIM is a nano then it'll be too small to fit into the new phone and the size difference would be obvious.
What make and model of phone were you using before?
Did you try the other suggestions that I made above?
iPhone 5 does take a nano SIM so that's too small for the new phone unless you use a nano to micro SIM adaptor.
Strange that you didn't notice this before!
It would have saved a lot of time & confusion....
If you squeezed the nano SIM into the micro SIM tray then hopefully you haven't damaged the latter!
You need to either get a nano to micro SIM adapter (e.g.https://www.carphonewarehouse.com/cpw/micro-and-nano-sim-adapter-3-pack.html#!colour=black&dealType=... or available in most other phone repair stores) or get a replacement micro SIM - choose the swap not block option and when you get it you can follow the instructions for activating it:
Hope this helps.
