Data not working

[Jnr]

My Data doesn’t seem to be working. I’m been travelling all over Europe but here in Switzerland doesn’t work for me at all. It worked when I was in Germany, France, Netherlands, All over UK aswell. Just doesn’t seem to work here in Switzerland

Assuming you are a contract customer - have you been travelling for more than 63days without returning to the UK?

If so, data may be reduced and charged for, so your spend cap may be getting in the way, if you have one Guide: Spend caps on O2 as you will be out of tariff.

If PAYG: You need O2 Travel to use your phone in Switzerland which is chargeable at £1.99 per day so you need extra credit.

Your UK bundle won't work. 

 If you message O2 on Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG) , they should be able to help you with this.

Some other things to try:
Manually search for another network
Reboot the phone.

If still not working then contact O2 as above.

Good luck @Jnr.
