“The new shop on wheels has a full range of Batelco’s products and services onboard. A selection of mobile handsets will also be available from the shop. Additionally, customers can buy SimSim call credit, pay their bills and complete any Batelco transaction conveniently at the mobile van.The van boasts comfortable seating in elegant surroundings and additionally features built-in air conditioning and a DVD system.”
