We've received user reports and confirmed with T-Mobile's services team that T-Mobile will no longer directly support the Yeastar device.
Customers have reported intermittent success and failures, so it appears that this is in a transition period.
MVNO providers SIMs and accounts perform better than SIMs obtained direct from major carriers.
Contact
support@exele.com for more information.
We do not recommend the Yeastar modem for new installations of TopView, if you must use T-Mobile.
Alternatives
- Consider switching to an MVNO, some T-Mobile backed options are available. Contact support@exele.com for suggestions.
- For voice calls, there's the QikCell RCVX3 Router by tickioT. This device can provide a SIP extension for TopView voice notifications, contact Exele support or tickioT support for a SIP extension.
- For SMS notifications, consider our other SMS modem recommendations.
We are working with T-Mobile to see if they have an alternative device for SMS like there is for voice (above).
