Costa Rica's TDMA cellphone subscribers are refusing to switch to GSM
Around 73,000 users of an older TDMA network in Costa Rica are refusing to switch to the newer GSM network, despite several months of network problems.
Some of the problems the network has suffered are unsent messages, calls cut and lack of coverage in some areas. According to ICE the problems with the service is due to needed maintenance, causing problems with the frequencies assigned to the TDMA.
The TDMA network is due to be switched off at the end of this year, but the company confirmed this cannot happen until the customers have migrated to the newer system.
