Can I get back deleted texts on my Huawei P Smart

I've deleted a text from a number which I need. I've been to Huawei and Vodafone but they say they can't do it. I've been searching tools online but getting nowhere. Is there any way to do this? I don't have an SMS backup tool on the phone as far as I'm aware although I've found backup to Google on showing SMS text messages. Thanks

There is software that may be able to do it, if the cost is acceptable to you.

For the future, you should install SMS Backup & Restore (and SMS to Text if you want readable copies).

As an end-user of the phone, there is no way to undelete SMS messages.
