Cell phone users could suffer more frequent interruptions in service beginning today through the end of the year as the Costa Rican Electricity Institute (ICE) works on its cell towers, this state-run telecommunications monopoly announced Friday in a statement.

Today through Dec. 14, ICE will be working on towers around the country to “notably improve the quality of service,” the statement said. The institute is working to accommodate the additional 300,000 GSM technology cell phone lines scheduled to become available in January.

In the meantime, users can expect spotty service and more dropped calls. ICE will be working on the towers during hours with less call traffic to lessen the inconvenience, the statement said.
