Mobile coverage

Bangladesh adopted the second generation cellular telephone technology or 2G network coverage in 1992, which for the first time allowed to start using digital encryption of conversations. 2G networks were the first to offer data services and SMS text messaging, but the data transfer rates were lower.

In 2013, 3G networks succeeded 2G, offering faster data transfer rates and enabled video calls for the first time. This was suitable for users having smartphones, which require a constant high-speed Internet connection for many of their applications. Despite some limitations, the third generation mobile phone technology drastically changed the mobile communication system.

However, the introduction of 4G in February 2018 added even new impetus to the mobile communication spectrum. The fourth generation of communication technology is able to provide ultra-broadband Internet access for mobile devices. The high data transfer rates make 4G networks suitable for use as USB wireless modems for laptops and even home Internet access.

All the telecom operators claim to have full network coverage throughout the country. However, the 4G network rollout is still actually in progress and it will take two to three years to cover the entire country. Many users these days allege about network problems. Urban users are enjoying this latest technology while in the rural and remote areas people still use 3G and 2G networks.
