Robi started to convert all their SIMs into 4G in last February and from the current month, after being merged with Robi, Airtel, too, initiated the same project.
The mobile phone operators, as a preparation of initiating telecommunication services of the next generation in the country, already started to convert their subscribers’ SIMs into 4G. Previously, Grameenphone also initiated this procedure for their subscribers and now, they are getting responses enough, as souce confirmed.
But, still no activities are observed from Banglalink and Teletalk regarding this 4G service issue. Airtel has been informing their subscribers to convert their SIMs into 4G through a declaration in their Face book page and sending sms since last August 1.
