Looking for cheaper internet and phone service.

We currently pay $80 for Xfinity internet and I pay $100 a month for my phone. I used to use AT&T prepaid but switched to postpaid a year ago. Unlimited post paid is $50 a month. We travel a lot so unlimited is a requirement and it just use AT&T towers as Verizon doesn’t not work well here and T-Mobile doesn’t work at all. We are expecting our first baby in February and I’m $1750 away from paying my car off so I’m looking for ways to save as much as possible.
