2023.04.12: SIM usage recommendation update

We would like to inform you about the SIM usage recommendation change - due to SIM card market tendencies (Standard size SIM cards being made to split to 3 parts) FMC640 First Start

Recommendation description
Recommendation reason	Due to SIM card market tendencies (Standard size SIM cards being made to split to 3 parts)
Detailed description	New paragraph about SIM usage is added to product First Start description. Previously SIM insertion recommendation was only described in schematics - SIM1 shown in lower slot, SIM2 in upper slot. Due to SIM market tendencies the documentation was updated to more clearly state SIM1 and SIM2 usage recommendations: 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

Change impact
Risk assessment	Recommendation updated to mitigate risk.
Suggested implementation plan	If you used one SIM card and it's placed in SIM1 slot (lower) - no implementation plan needed. If you used 2 SIM cards - SIM1 in lower slot, SIM2 in upper slot - no implementation plan needed. If you used eSIM - no implementation plan needed. If you used one SIM card and it is inserted into SIM2 slot (upper) - to mitigate risk of bad operator connectivity due to SIM construction - for future installations - when only 1 SIM card is used - insert it into SIM1 slot (lower) Additionally: If possible - ask operator for Standard SIM card with solid construction (not pre-cut to 3 parts)
