No need for immediate action, however, something for those with 4G LTE only phones to start thinking about…
Thankfully all my phones are 5G capable for the family, even our backup phone.
Looks like my Mom will be upgrading from an iPhone SE 2 to an SE 3
Thank you @rolandh for the specific information about T-Mobile phasing out LTE!
Just yesterday I came across a related discussion on Reddit. Other users of T-Mobile Home Internet (TMHI) have received email notices that they should exchange their “modem” devices for a newer version. Since we are still, since 2021, using the early Nokia “trash can” Gateway device to connect (quite satisfactory for our usage) that will happen to us, sometime. Apparently our trash can is not capable of 5G SA, only 5G NSA. At the moment it is connected via B66 and n41.
Looks like my experiments with a Nokia dumb flip phone with only LTE will wind down, too.
Progress.
