SIM card problem Rain

After a promising beginning, SIM card stopped working and no internet access for 5 days. Rain support completely absent. After reviewing a number of similar complaints, heard adjusting the SIM card helped but no progress for me. Today, hooray, by ensuring your SIM card is tucked under the SIM slot lip, so that the base of the card is not exposed, you find a sustainable position for internet access. Whilst I didn't do this initially, I still managed access. Only correct way forward, no assistance from Rain.
