Mine has completely given up on me and is saying I need to pay £14 for a new number
Make sure that your existing number is fully deleted
Choose ‘numbers’, click the arrow next to your number, then at the bottom choose ‘delete number’ then again at the very bottom of the ‘are you sure?’ Screen click the small print ‘delete this number’
You should then have a ‘get a 1st phone number’, choose ‘new local number’, pick a number ….
If you get the ‘secure this number’ countdown then it may be that your last number did not get deleted or you have changed too many for the moment
(I’ve just deleted & replaced numbers a few times to test it out and currently am getting the ‘secure this number’ page)
Another thing to try is to check that you have plenty of credits - Within the app choose ‘store’, ‘free’ and play some adverts (sometimes it runs out of adverts for you, so try again later)
Originally I ran a few adverts one after the other, putting my phone down with the volume down just to keep playing them, but now I have a good number of credits it tends to stay steady with free credits when SPs reply to messages, confirm the address etc
Check that push notifications have not been disabled for the app in your phones settings, or check for VPNs to make sure that you aren’t showing as in a different country etc
