Just recently I have been getting messages saying no sim card when the sim card is definitely in the phone, over the past four or five days I now get messages saying emergency calls only. Both of theses messages are intermittent and sometimes my phone even works!. Any suggestions as to what the problem is.
Thanks AxexKid, yes have already tried giving the sim a wipe and that doesn't seem to make much difference. Unfortunately I don't have access to another phone with a nano sim so can't try it out elsewhere.
