Sim card not detected

[KirstyPi]

Hi, sorry if this or a similar query has been posted here before, but I'm trying to just find a fix for the problem I've been having.

I've had a mobile wifi device with Vodafone for just under a month now and it's worked fine. However, today when I've tried to use it, I'm getting an error message to say that the SIM card is not detected. I've not taken the back off or moved the SIM card prior to this, so I found it a bit odd. 

I've tried removing and reinserting the SIM I don't know how many times, but I just can't get anywhere with this. Has anyone else had this issue and how did you resolve it, please?

Thank you

Try cleaning the chip on the card carefully with a soft cloth @KirstyPi

As a process of elimination can you try your sim card in another device or phone and try another sim in the device.

It could be the sim card degrading.

Any Vodafone Highstreet Store can look at the device and if necessary sim swap to replace the current sim card.
