Before you make the switch you need to think about a few things.
Having good cellular service has become an important thing for most people. We use our phones for everything from keeping in touch to keeping entertained when we have a few quiet moments. It's pretty great that we have such powerful machines in our pockets and nobody is happy when their service lets them down. That's why it's worth taking your time and checking out a few things before you switch carriers.
This can be especially important when switching to a prepaid alternative carrier, also known as an MVNO. Because they aren't the ones installing new facilities and building out the physical networks they operate on, they sometimes have to do things a little differently. These differences usually mean the service is cheaper every month, but it can also pose a few problems if you haven't done your homework before you made the switch.
That's what we're here for! Android phones and the service that powers them is our job and our hobby. We love to get in the mix and try things like switching away from the Big Four as much as we like writing about it. With that in mind, here are some things you need to think about when you're ready to switch to an MVNO as your new carrier.
Picking the carrier that works where you need it to
This needs to be the first thing you look at. MVNOs have the luxury of using the networks the Big Four have rolled out, and we all know that not everyone has equal coverage on every carrier.
One of the best things you can do is talk to people you know and see what service they are using. If you hear a lot of praise for one particular carrier and complaints about another, you have a good starting point when it comes to picking the right MVNO. You can also check out the carrier coverage maps.
- AT&T's U.S. coverage map
- Sprint's U.S. coverage map
- T-Mobile's U.S. coverage map
- Verizon's U.S. coverage map
You need to make sure you know what you're looking at here. Nobody is trying to deceive you but they all want their map to look as good as it can. On each of the coverage map sites, you'll find some controls to filter the different types of coverage that are being shown. Make sure to have a look and compare the voice calling maps to the data connection maps, and make sure you are filtering to see the high-speed data coverage. And definitely make sure you're not looking at "partner" or roaming maps, as many MVNO carriers don't support that part of their parent carrier's coverage.
Finally, be cautious if you need to use your phone in areas on the fringe or edge of coverage maps. The maps are never exact, and if the map tells you service will degrade just a few blocks from where you need to be covered, you might not get service at all. These maps should be considered as a good estimate rather than any sort of exact science.
Match your phone with the right network
One of the best parts about using an MVNO is that you can save even more money by using the phone you already paid for. As long as your phone works on at least one of the Big Four carriers in the U.S. there's an MVNO that offers great service for you.
It's not that difficult to make sure the MVNO you want to use supports the phone you already have. If you're up on all the technical jargon you can check the radio bands on your phone against the radio bands listed on every alternative carrier's website. You'll usually find these on the FAQ portion and if they match you're in business.
If you don't want to get bogged down in frequency numbers and all the different network bands, sites like WillMyPhoneWork can tell you if your phone is compatible with most any network worldwide.
We've built a list of popular MVNO carriers and which networks they operate on that can answer many of your questions right away!
You might need to get your phone unlocked
Most phones will need to be SIM unlocked before they can be used on another carrier. This has nothing to do with your phone's security (that's a different type of unlocking) and only lets your phone accept programming for a new network. Carriers have their phones SIM locked as a way to cut down on equipment loss — a locked phone only works on the carrier who locked it, and only as long as you're making the payments.
SIM unlocking won't affect your phones security.
In the U.S. carriers are required to unlock a phone once it's paid for. Most will also unlock a phone after you've been a customer for a while as a show of good faith. You can get your phone unlocked by the carrier by making a phone call or going into a store. Customer service will be happy to help you provided you've met any obligations they require. Because of some rules for using the frequency Verizon uses for 4G service, they are required to sell all their phones unlocked.
There are also third-party unlocking services that will send you a code to unlock your phone. If you go this route, be sure to do a quick web search on the company to make sure they have decent customer feedback. Getting your phone unlocked by a third party is exactly the same as having a carrier do it; once the code is entered you're good and can use a phone on any compatible network.
Know how much data you need
Most of us don't need unlimited data. The Big Four have brought back unlimited plans for the people who do need them, and we think that's great! But if you're not someone who needs a ton of data every month you're probably overpaying if you sign up for one of them.
You can check how much data you've used recently pretty easily. Your phone has a setting in the Wireless and networks section that tells you how much you have used in the past 30 days, but it's a good idea to get a bigger sample size here. At your carrier's website you should find a statement for the past few months that will show how much data each phone number on the account used. Get an average for the past couple of months, then add 1GB to it for a "just in case" bumper.
Take this number and look at the MVNO you're considering. Chances are there is a plan that will cover what you need. The best part? You don't have a contract and can adjust things next month if you need to!
What happens if you use all of your data for the month?
Life isn't static. Even with careful planning you might have a month where you had to use more data than you budgeted. It's important to know what happens and how you can add more data on a temporary basis.
Most every MVNO will sell "extra" data in 1GB increments. It's usually a little more than it would be if it were bundled into a pre-packged plan, but it won't be outrageous. Most companies charge about $10 per GB.
Buying extra data is always easy, but make sure you know how to do it before you need it.
What you need to do is check how you can add it right from your phone, so when you're close to using your allotted amount you can tap a few buttons and fill up your data bucket. You'll find this information on the company's website along with any other services they offer, such as international roaming or auto-refilling.
This is important because MVNOs aren't like the Big Four, and won't keep you connected then charge you overage fees (the good part) and instead usually cut you off completely once you've used all you have paid for (the bad part). Don't get stuck with no data and no way to buy more!
Some things cost extra or are not available
Wireless carriers can be strict about what they allow on their networks, and MVNOs are no different. Their business model — buy wireless service in bulk and resell with no frills — means they will have some restrictions on what you can and can't do, like tethering your phone or using your phone to call and text with someone outside of the U.S.
Chances are none of us are planning to run a server from our phone, but if you want to tether a laptop or tablet through your phone once in a while or call and text relatives in Mexico, you need to know the rules so you know what to expect. Many MVNOs will have simple and cost effective add-ons you can apply if you need more than just the basic service.
Just take the time to read the terms and see what you can and can't do while using the service. If you're unsure of anything you see, call or chat with a sales rep through the website and get squared away.
Advanced features may not work
Many of us have phones that support things like HD voice calls (VoLTE) or Wi-Fi calling. They're nice features if you use them regularly, but most of the time they are very phone and network specific. An MVNO may not have them at all, or you may need phones designed to run on a specific carrier to use them.
Advanced calling features require very specific phones.
This works the same way for the Big Four. If you want Verizon's HD Voice, for example, you'll need to have a phone that says Verizon on the back because it was built to the carrier's specs to use the service. Because most MVNOs don't sell phones under their own brand, you'll have to investigate if any of the features they offer need a specific brand of phone.
Mint SIM offers Wi-Fi calling, and it works really well — as long as you have a phone that supports T-Mobile's Wi-Fi calling feature. Verizon offers its own Wi-Fi calling but it's not supported on Mint SIM. Most phones that support Wi-Fi calling are built to work on both networks so you're OK with either a Verizon or T-Mobile phone, but not a Sprint or an AT&T phone. It can be a little confusing even to smartphone veterans!
You don't need any of these extras to have good, cheap cellular service. That's the best part. But if you see something you don't understand, you can drop a question in the comments and someone can help give you an answer.
Prioritization is a thing
Prioritization means a carrier like T-Mobile identifies which phones using the network are doing it through an MVNO and gives priority to their direct customers. Only a certain number of phones can be connected to a cell tower at a time, and we're always switching on and off to make sure everyone has a turn. We've all probably been somewhere that a lot of people were using their phones and the service got really slow — that's because the lines to get your turn were long and you noticed the wait time.
When things get extreme, MVNO customers can experience even slower service because direct customers are given priority. I use MVNO carriers almost exclusively because I love the value they offer. But I do get to see prioritization in action every year on The Mall in Washington, D.C. during the annual July Fourth celebration. There are three-quarters of a million people jammed into a four block area, and we're all on our phones. Folks who pay AT&T (for example) directly for service have very poor service. People like me using an MVNO have practically no service.
There's nothing you can do about this, and no secret hack you see on the internet is going to work. It just happens when there are way too many people using just a few towers. The rest of the year I get the same service I would have from one of the Big Four at a much lower price.
Bonus number 9 thing!
You're going to have extra money every month. You'll have the service you are used to in most every way, but it costs a lot less and you only have to pay for the amount you'll need. Some MVNOs only charge you for the exact amount you use!
Saving enough for a nice night on the town because you switched phone companies is a great feeling. You'll love it.
