Cellular providers for North Katy area?

Hi! I’ve always had T-Mobile and it was usually fine. However, I recently moved to Katy and the service had been downright s**t. I have spotty service at home which is closer to I 10 but I work a bit more north of Clay and in the Elyson neighborhood and I can’t even use my phone unless I’m in a building with wifi. Which means if I need to use the internet or make calls for work related or personal things in between locations during the day I literally can’t.

For those who live in this area, which cell phone provider do you have and how is the coverage. I’ve gotten frustrated one too many times and need to finally change providers.

Thank you!
