issue to verify number

Hello, so I can to presents My friend from discord who is unable to verify his number.He tried to verify his number multiple times but he failed . He called the number , but it doesn't reflect onto the site

make sure he can make international calls.

he is capable of doing that, he is using the same number as before in MPL, his user is MineCoderSam

miss off the 0 so for example instead of 07777 it would be 7777 as the 0 is taken from the country code to be added or go to mpl and see how the number looks there

i solved thanks everyone

even if i had credit balance of 0.50€, it wasn't enough so i charged more and it worked
