Why can't I send a text message to Lao Ka?

Check the hardware problem of the mobile phone first, and then check whether it is in the service area or the mobile phone is in arrears.

There are four operators in Laos: Unitel (9 prefix 9), LTC (5 prefix 5), ETL (2 prefix 2) and Tplus (7 prefix 7). Laos is different from other countries. Laos is divided into network card and telephone card. The advantage of the network card is that the internet traffic package is cheap, but you can't make phone calls or send text messages. The advantage of calling cards is that you can make phone calls and send short messages (about 4 yuan a minute for international calls), but the internet package is more expensive.
