Thanks for using the forums to get this looked into with your mobile service whilst abroad.
I am sorry you are not receiving texts or phone calls with passcodes to access your PayPal account.
The first thing I would do is see if you have WIFI calling enabled on your handset - this can sometimes interfere with receiving verification texts. It can still take some time for the texts to come through after switching this off.
Can I ask if this issue is only occurring with PayPal?
Do you have a friend or family's phone to swap the SIM card in to see if the text comes through? If it does, it may mean your SIM is faulty and you'll need to get a replacement when you're back in the UK.
So i have given myself a spending cap of £5 just to see if i can call. But it still does not call. Paypal have also claimed that they are sending passcodes (which i have still not received any) but all other companies managed to send their passcodes and i have recieved them.
Thanks for coming back to me and for increasing your spend cap, however I believe £5 may not be enough room still as the call charges per minute in Oman are £5, so this may be why it's still not allowing you to connect. I have a link here that gives you more info about charges whilst in Oman - Roaming Costs In Oman.
As for the texts, if other companies are able to send their texts to your phone, I would say the issue may be with PayPal or your spending cap.
Please do not increase your spending cap if you do not think you can afford the extra charges.
So I have increased my cap to £20. And i am still unable to ring to paypal (as a test to see if the cap increase worked) I feel paypal have said its my providers end and virgin have said its paypals end. Im gonna keep getting bounced between who is the issue. Though i do agree in my opinion its paypals end.
