I'm currently outside the country and have registered to GROAM before leaving. The problem is my SIM has not successfully connected to any partner network since my arrival (around a week ago). When I try searching for available networks, they get displayed but once I try to register, the process indicating that my SIM is registering appears, but in the end cannot connect to it. I've already used this SIM abroad in the past on the same phone, and I have been able to connect it during that time.
Hoping you guys could help me on this. Thank you in advance!
