Plus continues to modernize its network, consistently developing 4G/LTE and 5G technologies. The process of switching off the 3G network will begin in December 2026, but it is already worth checking whether the phone currently in use will need to be replaced.
In December 2026, Plus will start the shutdown of 3G technology. Replacing 3G with 4G/LTE and 5G is a natural stage in network development, allowing for more efficient use of spectrum and further improvement in service quality. The released resources will support the expansion of 4G/LTE and 5G networks, providing Plus customers with faster and more stable mobile internet as well as improved voice call quality. While the change will be unnoticeable for most customers, there is still a group of users who rely on SIM cards or phones that do not support modern 4G/LTE and 5G technologies.
Support During the Transition
In connection with the planned shutdown of 3G technology, Plus is implementing a range of solutions to help customers prepare for the upcoming changes. Each user can easily check on their own whether the SIM card and phone they currently use are ready for this change—simply by sending a free SMS.
Detailed information, including instructions on how to send the SMS, is available on the dedicated website: www.plus.pl/lp/wylaczenie-3g . The site brings together key information in one place, along with practical tips and answers to frequently asked questions regarding the replacement of the 3G network. Customers can also count on professional support from advisors at authorized Plus and Polsat Box sales points.
