Unable to make and receive calls and some problems with texts

Since last week I have been unable to make calls on my phone and at times have not been able to receive them.

When trying to dial out I receive the error message: call failure, the call could not be connected, please try again later.

This seems to happen whether I am dialing an O2 number or other networks and local/national numbers.

I have received a couple of calls from other networks and local/national numbers but had problems with people dialing in from O2. When people using O2 tried to contact me they were diverted straight to voicemail and sometimes I received a text to say I had a missed call.

I have also had problems at times sending and receiving texts.

I have looked online where people suggest looking at call forwarding settings but when I go to that screen I get an error and am unable to access the settings.

Anyone any ideas?

After much playing around with my settings all evening I have finally been able to make a call now I have changed the network mode to 2G.
Previously I have had this set as 3G and 2G for at least 4 years and have had no problems.
Anyone know what this means - is it something I've inadvertently done, a phone problem or a problem with O2?

@Nightowl It means that the old mast gives you a better signal on 2G rather than 3G or 4G. When the new mast goes live, you should get a better signal in your area.

I DO NOT WORK FOR O2

@Bambino Thanks that's good to hear. It says online that they are doing maintenance on the mast/s next week with the new one due to go live on 1st July so I can only assume it is a knock on effect from that as I'd had no problems until last week!
Just glad I have found a way to make calls in the meantime!

It's not a phone problem ut it may be worth calling into your nearest O2 store and getting a new sim card just to make sure there is no problem with it. I would hope they are upgrading the mast in your area but until then leave it on 2G when you are home.

@jonsie Thanks, yes I will go into O2 next week as my sim is quite old so definitely worth them checking / changing it.

Here are some of the checks i would do as a guru.

 

1. Try your sim in another phone.

2. Try another sim in your phone to see if the handset is fine or not

3. When visiting other area check your signal and services to see if they resume.

4.Have you tried selecting a network manually on your device?

5. Turn 4g of and try 2g/3g

6. Potentially a sim swap

 

If you have done everything above you essentially cannot do anymore, Then you would need to get intouch with the gurus to raise a change in service case which goes to the engineers and they take it from there.

 If indeed you are an O2 Guru @EducatedDevice, you need to put that in your signature along with a disclaimer.

@Martin-O2@Marjo@EmilieTcan advise further.

Update - I went into my local O2 store today and did a sim swap and all seems to be working again now.

Thank you all for your help.

Fingers crossed for you and glad I could help.
