I have developed an application for GIS Survey of Electricity Poles in
I have been able to test all features and have deployed the Mobile App on
two Android Phones (One with SIM and one phone deliberately without a SIM
to depict no mobile connectivity scenario) and carried out GIS Survey.
The problem that I experience that the Phone without SIM did not capture
Geo location of electricity poles (using the mobile App) where as the phone
with SIM had no issues.
The capability for the mobile user to working low connectivity/no
connectivity environment is one of the requirements of the Customer.
I was always under the impression that each mobile phone has a GPS Receiver
and there should have been no issue in capturing Geo Location (even if
there was no SIM). Moreover, on opening Google Maps (on phone without
Sim), the phone shows being connected to GPS - Blue colored Icon.
Can someone please throw more light on this and guide as to how this issue
can be resolved.
Thanks in Advance
