The network is the most important thing when choosing a cell phone plan. Signing up for a phone plan is not a good idea if you can't use it all the time.

Some rural areas still prefer one carrier over the others, despite the fact that all carriers have made huge strides in recent years. Rural areas tend to have greater coverage for 5G than urban areas. You will need to check out the coverage maps before you sign up.


If you prefer a carrier's network but not its plans, it's time to check out an alternative. If you want to save money, you should get rid of the features and services you don't need and get a simpler phone plan from the bestMVNOs. If you know that you need the T-Mobile network, you can choose an MVNO that's based on that network.

AT&T is not the cheapest carrier, but it does offer a number of valuable extras, like the unlimited elite plan. Six months of Stadia for free is offered by new lines. If you are eligible, the Signature Program members can save more.

If you want to switch to T-Mobile, you should use a 5G phone. While T-Mobile's network is solid, higher and more consistent speeds are unlocked with a 5G capable device. T-Mobile has a plan for older customers that will save them money.

If you bring the entire family with you, you can likely save more than if everyone uses their own account. Some great deals are available if you sign up for the service.

Most unlocked phones on AT&T will work with 3G and 4GLTE with a simple swap of the phone's sim card. All of the information the phone needs to connect to AT&T's network should be carried by the sim card. It is possible that you need to manually enter the settings yourself. This information will be filled automatically in most instances. If you want to make sure your phone is compatible, you can check it on the AT&T website. Some 5G phones won't be allowed by software to connect if you check with AT&T.

It's the easiest way to find out if it's true.

You might not be able to take the phone with you if you don't have a carrier lock it on. The first thing to look out for is that you are not making payments. You will need to buy a new phone if you are. If you leased your phone through the manufacturer, this shouldn't apply.

You can check with your current carrier to see if you have any outstanding fees that need to be paid.

  • AT&T: (800) 331-0500 or 611 from your AT&T phone
  • T-Mobile or Sprint: (800) 937-8997 or 611 from your T-Mobile phone
  • Verizon: (800) 922-0204 or 611 from your Verizon phone
