Invalid sim?

[izzi277]

Ive been on 48 for 2 years with the same sim, no major problems. My phone was working for the whole day when 'invalid sim' instead of '48' came up at the top of the screen

Try switching off, reseating the sim and switching on again and see if that makes any difference.
Can you try the sim in another unlocked phone?
Are you using an iPhone by any chance? If so perhaps something has changed that necessitates the phone being reactivated on the network?

If all else fails then you probably need to contact 48 support about this or order a replacement sim.

Hope this helps.

You need to order a replacement SIM yourself:

Change my SIM

Hope this helps.

Thank you for your replay, i swiched off the phon and then on and the sim started working so no need for new one, thanks again

Strange, maybe worth getting a replacement anyway just in case?
If you choose the swap option then your current one will keep working and you don't have to activate the replacement unless the current one starts acting up again.

Hope this helps.
