6-7 months of travel this year, all West of the Mississippi.
We travel with multiple devices from ATT, Verizon, Millenicom (T-Mobile - Dormant until needed, then we pay for a month, or longer. Good company to work with.)
We still find locations where either Verizon will have coverage, and ATT won't; Or ATT will have coverage, and Verizon won't. I'd say the number of times one carrier worked, and the other did not - has dropped dramatically over the last 5 years. Verizon still is the best chance of obtaining coverage, but ATT has expanded so much lately, not near as often as what we experienced in the early RV'ing years. (Again, in the areas we travel.)
Suggest you call Verizon, tell them you are considering canceling your service, and ask to be forwarded to a Retention Specialist. Tell them you're concerned about the cost of your plan for what you are getting. And ask them if they can see anything that could be changed to either make it a better plan at the same cost, or lower the costs and keep the same attributes.
Never hurts to ask
!
And if planning on changing to someone else, suggest you wait a few months, as ATT is about to change their plans again, and that usually cycles thru to other carriers also tweaking their plans - in 'The Dance For The Customer'!
Best of luck to you,
