A reliable mobile carrier isn't a luxury anymore. Reliable access to calls, texts and the internet is now a daily necessity. You likely have an opinion about your cellphone plan, and we want to hear it -- the good and the not so good.

This month, we're asking which mobile carrier you rely on. You can take our two-minute survey to share your experience on your plan's reliability, speed, value and customer service. The top picks will make it to our roundup, so be sure to check back in a few weeks to see if your favorite made the list.

Why we want to hear from you

Advertised speeds and coverage maps don't tell the whole story. What matters is how your signal holds up in crowded spaces, on a road trip or even at home, and we want to know about your experience.

"It's easy to get overwhelmed with specs, especially when you're comparing phone plan features, but the real test is whether your service is working as you expect or getting in your way," said Jeff Carlson, CNET senior writer. "With so many variables -- your phone model, the cell towers in your area, even obstructions like buildings and trees -- each person's experience is going to be different."

Whether you're on a national network or a budget mobile virtual network operator, you can help other CNET readers find a reliable carrier by sharing your thoughts.

How to make your voice heard

This survey is open through the end of July and takes only a few minutes to complete. After we gather enough information, we'll crunch the numbers and publish the winners.
