2G Sunset & 3G Status Updates

Important information for Wireless Logic customers

With a number of key applications utilising 2G connectivity, particularly in the US, services in Singapore and Australia, the ‘sunset’ of these services has now commenced. AT & T has now concluded its sunset. To ensure that your SIM-based assets are unaffected or prepared for these changes, please read the following information. Whilst we will try to maintain this list as accurately as possible, we are not tracking each network globally for updates. Officially networks only need to give three months’ notice to confirm the shutdown of 2G.

We are also featuring 3G status updates on this page. For more information on 3G news, see below.

The Wireless Logic team are on hand to talk through the impact in detail and are ready to propose alternative strategies if you are affected. Call 0330 056 3300.

When and why?

With two principle technologies powering 2G – GSM & CDMA, both have been hit with the proliferation of 4G driven by data-hungry mobile devices and applications. Whilst CDMA has coped by sharing their spectrum with 3G and freeing up capacity for 4G deployment, GSM has been less fortunate with providers having to eventually ‘sunset’ 2G networks in favour of 3G/4G LTE.

The impact

Whilst some carriers will continue to support the 2G spectrum up to around 2020/2021, the inevitability is that users must now start the transition process. For some, technology in use may be coming to its natural end. For others, the costs of decommissioning, upgrading and/or complete replacement of devices must be considered.

And where applications simply don’t need the capacity of the new spectrums, it’s important to consider the long-term impact of the 2G sunset. This may involve migration, SIM-swap to networks still committed for the mid-term, or device change.

Next steps

With key decisions to be made, Wireless Logic will be on hand to review current deployments and lay out the most appropriate strategies to ensure business continuity, at the right cost. With a number of customers utilising both national and global 2G connections in US-based projects, now is the time to talk.

Three have confirmed they will be switching off 3G but have no firm dates at the moment.

Three are reframing 2 of the 3 blocks of 3G spectrum on some cell sites to help improve 4G coverage. Three Retail stopped selling 3G last year, at the time giving clear reasons that 3G was a technology that is on its way out.


AT&T has now shut down its 2G network.

AT&T From 31 December 2018 there will be no new 3G activations. All NEW activations must be LTE technology.

AT&T From 31 December 2018 they be terminating 2G and 3G roaming service with a roaming partner that services parts of Iowa, Wisconsin, Minnesota and Illinois. Any 2G and 3G devices located in the territory impacted by this roaming carrier service turndown are at risk of service disruption and should be upgraded to LTE or LTE-M capable devices before this date.

AT&T From January 2019 3G/UMTS began spectrum re-farming – the process where subject to spectrum demands, 3G coverage may be reduced earlier than the official date of February, 2022.

AT&T From February, 2022  3G/UMTS sunset. Note that AT&T roaming partners will continue to turn down their 3G networks in line with their own schedules. Users should take appropriate action to ensure applications and devices remain connected after this time. It is advised that when re-deploying with a new mobile network, users should build in ample time for development and compatibility testing.


Taiwan Mobile has now shut down its 2G network.
