Unfortunately lately firertc has many outages and stoped working like it used to in the past. After each outage you can’t call and when you try to call it rings none stop.
Texnow is blocked in some Europe countries although in some others is allowed to register with google and with facebook (which didn't really work for me)
textfree over pc only sms ;(
rebtel mobile app or call over a real phone using a rebtel access number. You can call with which ID you want but you have to spoof your ID by calling one of their access numbers.
Google hangouts, uses only Hidden CID to call. It is easilly blocked.
Now I'm out of free ideas :slap:
Any ideas of freebies that can help?
