As experienced, "in many cases",
Momok Kuning has similar experience as well. And if this happens, just Flight Mode On-Off will resolve this annoyance.
However, other factors also contribute to this pesky hand-shake problems such as the phone's modem, firmware, antenna design, signal booster & amplifier, weather, cell towers configurations, etc.
Me suggest U get a dummy SIM card to test. Put this dummy SIM in the SIM2 slot and test both SIM1 and SIM2 hand-shake experience.
In old phones (perhaps made before year 2018), the SIM1 slot has better priority in terms of modem performance. For current phones (mostly above mid-tiers level), both SIM1 and SIM2 slots has equal capabilities.
