@OOOF#76557 No. All US Internationals are +1.
@OOOF#76560 This is a problem that’s already been covered for a long time. They will not be taking any new account registrations due to the abusive use of the app by malicious parties.
There are other services wich work just as good as FireRTC. TextNow, Skype, Google Hangouts are just a few of them. What makes FireRTC stand out is the fact that you can spoof your Caller ID - meaning you can change your phone numbers as much as you want in order to bypass numbers who blocked your Caller ID (so you can keep annoying scammers as long as you want to). I'm not sure about Skype or Google Hangouts, but TextNow can't do such, and therefore FireRTC is the most popular among scambaiters.
Hope this helps. Happy hunting.
@Darrell64#76522 what does he ask for?
