Are there any reliable dealers of second-hand or refurbished cell-phones in Thailand?

May I ask why you want to go that way?

You can get a decent phone for 5000 baht and up.

I seen those phone stalls in supermarkets/shopping centres selling 2nd hand phones but doubt they will give you any warranty.

 

Buying second hand electronics in Thailand?  Are you nuts?

I find that the prices they want for them are near to or more than you could buy on Lazada anyway. Reason is they have probably had them a few months and when they bought them they were a good price but since the price of that phone new has probably gone down as it is superseded by a newer model.

 

Dunno how those little shops in the malls sell anything. Their prices for new phones are the same or dearer than in a reputable dealer (Banana, Jaymart etc) and warranty after sales service etc would have to be doubtful not to mention if the phone was a copy or grey market. They must sell ok though because there are plenty of them around 

To buy from Lazada users should carefully check the Warranty for any single product! Many of them even didn't have any Warranty, except the 7-day Return Policy!
