just inserted new sim in an iphone 5 and done a sim swap. now calls are flaky and can't send texts....any ideas?
Please try rebooting your device as this fixes many issues.
If that has not solved your issue then check if there is any network maintenance affecting your service by going to http://tinyurl.com/giffgaff-service-checker
Or on a mobile device check here http://giffgaff.hourb.com/
still no good - but many tks for trying!
had to factory reset iphone 5 then resync what i needed back onto phone.
works brilliantly now
tks for suggestions everyone!!!
