FMX6 devices use Standard size SIM cards for SIM1 and SIM2. Currently most of the SIM
cards provided by operators can be disassembled into 3 parts - Standard/Micro/Nano.
Depending on the SIM card construction - during device usage in harsh conditions, SIM
assembly might come apart which causes instability when connecting to operator.
To avoid such risk:
1) If possible - ask operator for Standard SIM card with solid construction (not pre-cut to 3
parts)
2) Do not use SIM cards that were previously disassembled (SIM was taken apart
previously)
3) If you plan to use only one SIM card - insert it into SIM1 slot (lower slot) - this ensures
greater pressure on SIM contacts as the contact bed is pushed by PCB.
When 2 SIM cards are used simultaneously risk is mitigated as well - when SIM1 is
inserted, a greater pressure is applied for SIM2, so SIM parts are harder to come lose
