Which prepaid SIM card in Thailand is the most profitable for internet for a month?

The most profitable tariff for internet for a month in Thailand is Dtac 7-Eleven sim (ex. HAPPY Combo SIM) for 199 baht (about 456 rubles). It gives 30 GB at 15 Mbps speed, after which the speed drops to 384 Kbps (unlimited), plus 30 minutes of calls to all networks and unlimited WiFi in the city. Validity period is 30 days. If you need more traffic, consider Kongkrapan Sim from True Move for 650 baht — 100 GB for 3 months.

For short trips of 7-14 days, the Dtac 7-Eleven sim for 49 baht with 3 GB may be suitable. It is valid for 7 days and gives only 3 GB of traffic, but it can be extended by topping up the card at supermarket counters for another 50 baht. Combined with hotel WiFi, this total volume of 6 GB for two weeks is enough if you do not watch videos or download many photos. Also, the tariff includes unlimited data when connecting to city WiFi.
