Re: SIM900 - No registration to network

I have the same problem(no registration or very unstable with low signal) with some of my Geetech sim900 modules.... I did the same thing like hotkebab99 describes few posts back... success.... it is working now.... Looks like this module have some problems with antenna connector...
