Topkapi voice synthesis on-call: discontinuation of Yeastar 2G and 3G GSM modems

9 December 2025

Topkapi information

Manufacturer YEASTAR has announced that it will soon discontinue sales of its TG100 GSM, TG200 GSM and TG400 GSM modems. This decision follows the planned shutdown of 2G and 3G networks by telecom operators between April 2026 and December 2029.

These modems, which only support GSM (2G) and UMTS (3G) networks, are now being replaced by the new TGxxxL LTE/4G range. The replacement model recommended by AREAL for Topkapi voice synthesis on-call systems is the TG200L LTE/4G.
AREAL is currently evaluating this equipment and will soon update its documentation to include it.

This move towards 4G is part of the broader context of the gradual phasing out of older generations of mobile networks in France. It is recommended that you plan to replace the equipment concerned before the operators' final shutdown dates.
