Roaming not working

[Natali]

Hi I’m in turkey and my phone not roaming 

[pgn]

Assuming you are on Pay Monthly contract with O2: Roaming in Turkey will be expensive with O2 unless you are on one of O2's most expensive "ultimate" tariffs: https://www.o2.co.uk/international/using-your-phone-abroad or have the £7/day O2 Travel bolt-on.

As mentioned above:

Check your phone's APN is "mobile.o2.co.uk" 

Make sure you are using 4G (5G should work too, but 3G may be patchy).

Set your phone manually to a cellular network

Ensure you have Data Roaming enabled (as well as roaming).

Finally, contact O2 via Social Media or the free to call from an O2 phone +447860980202, to get them to check you have not got a Roaming Bar in place on your phone - seems many have had that setting inadvertently applied if you upgraded in last 24 months or so.

Try to manually connect to any available network, even one that says "Forbidden".

Good luck, @Natali
