This is a new out of box FXT009,
The unit seems to struggle to auto register to “UK 02” and seems flaky when it is connected.
sending +++ATZ also seems to often result in “ERROR” if a previous command had failed ( especial when trying to use the “O2” Sim.
I have seen instances of “at+csq” reporting “99,99” and saw a fix in one of the firmware versions relating to this and requiring a cold restart.
I was hoping a firmware upgrade would make the unit work more reliable, especially with the “02” SIM
Cheers
Rob
