Hi, I am Stephan from Germany. I just finished my Ringo Phone (I gave it to me myself for Christmas), but I have problems to make calls. I use a T-Mobile SIM from my iPhone (so I know itâs working). Ringo does find the network (signal strength 20), but I only can call one number - my wifeâs mobile phone number. Every other telephone number I call - with or without the +49 for Germany) is terminated directly after starting the call. The display show âcall endedâ and thatâs it. It makes no difference if I type in the number directly or if I use âcontactsâ.
My Ringo is equipped with the SIM800 = 2G, I updated via WiFi to firmware 1.0.5. All solderings look good, I double-checked it.
Wht can I do to make my Ringo work - itâs to expensive to throw it in the trash.
Best regards, Stephan
