Did you receive an email about unsupported routers in the past year, @Gerry121?

The text may be referring to that, but in case it's a scam, call 03451 720088 between 9am and 7pm weekdays or 6pm on Saturday.
Don't reply to the text.
There is an £80 charge if you want to update to a properly supported router unless you are about to renew your contract (in which case it should simply be replaced) or if there are faults diagnosed with the current one.

From the 29th of March our TalkTalk Community will move to peer-to-peer support and the TalkTalk team will no longer be here to support with queries. Don’t worry we still have plenty of ways to reach out if you need to speak to TalkTalk directly. For more details check out the link in the post at the top of any forum message board.
