you just need to have a photo on your phone of your current visa, anyone saying carry your passport around, it's not them that has to deal with it, if it goes missing!! if you live in Thailand and your current visa is due to expire, you would need to return to your home country, to avoid being on overstay, and to get a new passport, at great expense and a lot of messing around you can do without.
