Druknet, a subsidiary of Bhutan Telecom, is the exclusive and primary Internet service provider for Bhutan. The development of the internet in Bhutan has a very interesting history. Despite the fact that telecommunications services began in 1963, the country's first access to the internet, using Gopher as the browser, didn't happen until 1994. PINE was the mail system at the time, and there was no www, but the general population did not use the internet. The Bhutanese government ordered the country to have internet access within three months in 1999. On his 25th anniversary of becoming king, His Majesty Jigme Singye Wangchuk announced to the nation that Bhutanese citizens could now access the internet. At the Royal Banquet Hall in Thimphu, the then-queen, Her Majesty Ashi Dorji Wangmo Wangchuk, the king's first wife, formally launched the ritual. Bhutan had been hesitant to adopt the internet, but after making the choice, the entire project was finished and operational in just three months.
Today, the majority of Bhutan's major towns have a number of internet cafés. Additionally, it is now possible to access the internet using a Tashi Cell or B-Mobile SIM card via the 3G and 4G networks (state-owned Bhutan Telecom). The majority of hotels in Bhutan offer free Wi-Fi to visitors, albeit this service may only be used in the lobby and restaurants. When visiting places with spotty internet access, tourists have the choice of obtaining a local SIM card from the telecom department with the help of their tour guide and using the SIM's internet services, however, the network may occasionally be extremely sluggish.
In Bhutan, obtaining a 3G pre-activated SIM card is actually pretty simple. Travelers must submit copies of their passports for this, and they may also request a recent passport-sized photo. It won't cost you more than $4 USD to purchase the SIM at the airport upon arrival or from neighborhood stores in the market districts of Thimphu or Paro. Make sure you complete the form for a tourist SIM card, and if you need assistance, ask your tour guide.
