Cant receive texts or phone calls.

[Anonymous]

Apologies in advance for the long read.

I recently started a new contract with O2 3 weeks ago, and for the first week (at most) it was working absolutely fine. Then last week I discovered that I could send texts (although would take some time to reach the person) and couldnt make or receive phone calls. I did a SIM swap this weekend which allowed me to send texts properly but not receive them, and make phone calls but not receive them. I went back to the store where they tried my SIM in another phone which showed no different results, implying the SIM is the problem still. Last night I did another SIM swap and still nothing has changed. I tried the SIM in my old phone and the same problems are occurring - send but not receive texts, make but not receive phone calls.

I find it unlikely that 3 SIM cards in a row are faulty (bearing in mind the first one worked for a week), which to me means that either my phone is somehow corrupting or breaking the SIM card, or it is some sort of account problem that is allowing outgoing but not incoming phone traffic.

My next plan, unless somebody suggests otherwise is to attempt another SIM swap (number 3), but this time quarantine my current phone and put it straight into my old phone, or another that they have in the store perhaps - to eliminate the possibility that my phone is at fault.

Hi @Anonymous What sort of phone are you using?...and are you on contract or payg?

Also check your network status here http://status.o2.co.uk/

Its an LG G2 and its a contract. I checked the network status for the area and it says its all working normally.

Can you try your sim in another phone? If it works then its  probably an issue with the phone. (I know you say you did this once before but you are on your 3rd sim now). I am also wondering if you have been given the wrong type of sim. Contract and payg are different..

Well SIM number 2 the people in the store tried in a different phone on 2 separate times on 2 separate occasions that I took it there, as well as myself trying in my own old phone. And number 3 has been in my new phone and tried in my old phone as well. Until I can get back into the store again (probably this weekend), I have no other phones to try it in. I agree it seems likely that it is a problem with the phone as opposed to 3 separate SIM fails, which is why I think it might be worth trying yet another SIM swap but trying it in a different phone first, in case it IS my phone causing the problem which then spreads to the SIM. Either that or to, as was suggested by customer services when I spoke to them, try a different SIM that is known to definitely work, in my phone - unfortunately the people in the store said they didnt have any to try.

Also I would hope they would have noticed which type of SIM to give me, as I told them each time I was on contract and they had my account details open when they provided the SIM but I guess I cant be certain.

I am sure they should have known the correct sim @Anonymous but after so many fails I am just trying to rule things out step by step...

Have a look at your message centre number...

The message service centre settings are as follows:

+447802000332 for Pay Monthly
or
+447802092035 for Pay & Go

You'll need to check that the message centre number starts with +44 and not 0044

I know you are also having problems with calls...but again checking various options...

Again...if these are correct it points even more to a phone fault

What about trying someone else's sim? A friend also on O2 (or one of the O2 store staff's)?

Service centre address is +447802000332, so that should be correct for my contract.

I might ask one of the O2 staff next time im in there, whether they would feel comfortable with that im unsure. And my housemate was originally ok with the idea of trying his sim in my phone, but as soon as I mentioned (thinking out loud) the possibility that it was somehow my phone causing the problem with the sim, as farfetched as that may be, he decided not to try it.

If you tried your sim in another device It wouldn't corrupt the other phone. It would just prove it was your phone at fault as opposed to a sim fault. ...(If it worked ok in the other phone)
