So, I am from Serbia and I found on this forum that my country is not supported. OK, well, I had an account here before and on that account was possible to enter a phone number from Serbia, which I successfully did. So, because I decided to delete that account (because, dumb me, I thought that I can change name in any moment, which wasn’t possible), I created a new one and waited to add another phone number (because you can/t use the old one again).
So, as soon as I got a new SIM card, I tried to add it to my account so I could start selling. Oh, and that didn’t work - the message was PHONE NUMBER IS BLOCKED. Damn it! Ok, I then tried my wife’s number and again there was a message: PHONE NUMBER IS BLOCKED. So, then I made two more accounts just to try another combinations - one with with another mail, one with Google account. And the problem was consistent - PHONE NUMBER IS BLOCKED.
So, I made a dozens of account all over the web before, like PayPal, Bandcamp, Player Auctions, G2A, etc, and all these work just fine with my Serbian phone number. I was in a furious “WTF mode”.
Bonus in all these is that I’ve trying to find some solution over my phone, I’ve done all of these steps over the phone and it’s pretty annoying to do all this without keyboard and mouse (I was away from my personal laptop). At the end of this crazy journey, I sent a message to support to delete all of these accounts, I wrote them codes for all three of them. I don’t care if they delete them, I don’t have a problem to login/register with my Facebook account. I don’t have a problem to link my PayPal account. I just want to know how to link a phone number because it worked once without a problem, so it should work again.
