3G Cellular Network Retirement
Posted on July 14, 2021
AT&T has recently announced that it will discontinue its 3G cellular service by February 2022. Once AT&T’s 3G service is discontinued, Model S vehicles built before June 2015 without a 4G/LTE capable modem will not be able to enjoy the following features unless connected to Wi-Fi:
- Roadside assistance to unlock your vehicle remotely
- Certain mobile app capabilities, including Summon, cabin pre-conditioning, vehicle location, remote unlock, etc.
- Certain Infotainment features, including navigation, maps, live traffic updates, up-to-date Supercharger availability and outage information, online music streaming, and onboard map updates
- Over-the-air updates
In order to maintain cellular connectivity after AT&T discontinues its 3G network, your vehicle will need an LTE-capable modem. To purchase and have this modem installed by Tesla, simply schedule a service appointment through your Tesla mobile app. Select ‘Schedule Service’ > ‘Upgrades & Accessories’ > ‘LTE Upgrade.’ This LTE modem upgrade is available for $245 CAD plus applicable taxes and includes installation.
