LW40C - My AT&T GoPhone card no longer works with my device.
The LW40C requires a 2G network. Unfortunately, AT&T dropped their 2G network on 12/31/16.

However, we've found that T-Mobile is still supporting 2G until 2020 and verified their sim card works with the LW40C.
The T-Mobile sim starter kit is what we recommend. Tobii Dynavox does not sell this card but it can be purchased from T-Mobile or anyone else that carries these cards on their behalf. https://prepaid-phones.t-mobile.com/prepaid-phone/t-mobile-prepaid-3-in-1-sim-starter-kit?icid=WMD_PD_Q117BYODVR_9XRZU493P87464
If you need assistance activating the card, please contact T-Mobile for support.
Once the card is activated, Tobii Dynavox is happy to provide text messaging support on the device itself, though.
