I got this link from Sara at Straight Talk who PM'd me about my other question I had posted.

In this link it says the following:

We Have Great News!

We negotiated with our partner to extend the deadline until the Summer of 2020. You now have more time to purchase a phone compatible with the improved network. As always, we will be in touch with updates regarding the changes.

I still plan on buying a new phone before that time (just because I don't like having to do things last minute) but well, you know ...

Anyways, maybe y'all had heard about this already but it's the first that I had and so thought maybe others hadn't heard it either.

Here's the link: https://extras.straighttalk.com/en/1...1S1_01_SP_wk34
