Is there a reason I'm not getting my phone verification through?

I'm start starting up some accounts for a long term project, but one of them is not receiving the verification text. I'm just wandering if this is a common thing? I have checked the phone side of things and that receives text messages fine, so is something on the Facebook side of things.

what kind of phone number are you using to get the code? because facebook blocks a lot of voip services and free texting apps such as pinger and textnow. If you are using a real phone number with a sim card, their shouldn't be any problems. If so, than that number has been used already too many times with facebook.

It was a standard pay sim, in the end I just changed to a different sim and everything worked so much have been a network issue.

I had an account like that a while back and have no idea what the end was as I am not sure if I just tossed the account and moved on or if it was a sim issue.

Yours is the only other person that I have heard that happen to but for frustration sake I'd try the number on a new account and if that did not work send the sim card packing to the round file.
