AT/AirtelTigo Ghana roaming, etc
With an AT SIM, the phone automatically attempted to roam on MTN (62001). On 2G, this was successful. However, 3G triggers "Roaming not allowed in this location area", and 4G "No suitable cells in tracking area".
The phone indicates that
ehplmns=[] hplmns=[62003]
.If 62002 is selected, this leads to a normal result on 2G and 3G (though sometimes, on 3G, the value #22 "Congestion" is received). On 4G however, the value #17 "Network failure" is consistently received.
Coverage of 62003 2G appears to be reduced.
62002 might be indicated as either Telecel or AirtelTigo and 62003 as Tigo or AirtelTigo.
