Thanks for the update.
That seems odd - I don't know why it would make a difference which SIM tray was used.
And if you were only using a single SIM then I'd expect that the first SIM try would work.
I have a dual SIM phone myself (albeit not a OnePlus phone) and had no problems with this with my SIM in the main/first SIM tray.
I can't find anything online about this issue with the OnePlus 3T (or other models).
