Hi, I am getting this unifi mobile for my parents but they only know how to use basic phones with buttons such as Nokia 1100 or 1616. Do you know if unifi mobile is compatible with such old phones or any current basic phones with buttons?
i think their mobile services can be used on all phone models, however, they encourage you to use a certified phone to experience the best quality of service.
for your case, your parents can enjoy free calls and free sms only.
hope it helps
