Actually there is an old thread with similar title created by me in Feb 2023, but since that discussion is closed, I cannot add any comments.
I want to update to the community that I have been using Gigaset GS290 handsets with Indian Telecom Operator Jio with VoLTE, I am now able to make voice calls.
Details:
I have 2 GS290 handsets. Back in Feb 2023 VoLTE was not supported by Jio here in India and only 4g data was operational in the handset. After my few correspondences with Jio Telecom to support VoLTE, to my surprise, both the handsets actually were able to make phone / voice calls, roughly after July 2023.
Ever since then, till now, as on June 2025 I have been using both the Gigaset handsets with Jio and able to make VoLTE voice calls as well as access 4g data. There is no network issue with GS290 + Jio telecom.
