Roaming charges are fees your phone company adds when you use your phone outside your home network's coverage area

A roaming charge happens when your phone connects to another carrier's network instead of your own. Your home carrier then charges you extra for that connection. This most commonly occurs when you travel outside your home country — international roaming — but it can also happen when you travel to a remote area in the US where your carrier has no towers and your phone automatically connects to a competitor's network.

The charge appears on your bill as a separate line item, usually labeled "roaming" or "international roaming." The amount depends on what you do while roaming: making a call, sending a text, or using data each trigger their own charge, and they stack up quickly. A single text message sent while roaming internationally can cost $0.50 to $2. A phone call can run $1 to $3 per minute. Data roaming is often the biggest shock — using your phone to check email or load a webpage while roaming can cost $5 to $10 per megabyte in some countries.

Key Takeaways

  • Roaming charges apply when your phone connects to another carrier's network, most often when you travel outside the United States.
  • Calls, texts, and data each incur separate roaming charges, and costs vary widely by country and carrier.
  • You can avoid roaming charges by turning off data and cellular service before you travel, or by purchasing a roaming plan before you leave.
  • Most carriers offer roaming packages for specific countries or regions that cost less than pay-as-you-go rates.
  • If you see roaming charges you did not expect, contact your carrier within 30 days to dispute them.

How roaming charges appear on your bill

Roaming charges show up as individual line items under a "Roaming" or "International" section of your bill. Each call, text, or data session is listed separately with the date, time, duration (for calls), and the amount charged. If you made a call while roaming, you will see the call duration and per-minute rate. If you used data, you will see the amount of data consumed and the per-megabyte or per-kilobyte rate.

The total roaming charges are added to your regular monthly bill. Unlike overage charges for exceeding your plan's data limit, roaming charges do not count against your monthly allowance — they are billed on top of what you already pay. This means a $100 phone bill can jump to $150 or more if you used your phone while traveling without a roaming plan in place.

The difference between domestic and international roaming

Domestic roaming happens when you travel within the United States but your phone connects to a different carrier's network. This occurs most often in rural areas or small towns where your carrier has no coverage. Your phone automatically switches to the available network — usually without notifying you — and you incur roaming charges for any calls, texts, or data you use. Domestic roaming charges are typically lower than international charges, often $0.50 to $1 per minute for calls.

International roaming occurs when you travel outside the United States and your phone connects to a foreign carrier's network. These charges are significantly higher because your US carrier must pay the foreign carrier to use their infrastructure. International roaming charges can be 5 to 10 times higher than domestic rates. A call that costs $1 per minute domestically might cost $2 to $3 per minute internationally. Data roaming internationally is especially expensive — some carriers charge $10 or more per megabyte without a plan.

Why roaming charges are so high

Roaming charges exist because your carrier must pay the foreign carrier or the rural carrier to route your call, text, or data through their network. That cost is passed to you. International roaming is particularly expensive because foreign carriers charge your US carrier a wholesale rate that is much higher than what you pay for domestic service. Your carrier then marks up that wholesale cost and bills you.

The high cost also reflects the complexity of connecting across borders. When you call someone while roaming internationally, your call travels through multiple networks in multiple countries, each taking a cut. A text message sent while roaming internationally may pass through three or four different carriers before reaching the recipient. Data roaming requires constant negotiation between networks to maintain your connection, which costs the foreign carrier money and time.

How to avoid roaming charges before you travel

The simplest way to avoid roaming charges is to turn off cellular service and data before you leave. On an iPhone, go to Settings, then Cellular, and toggle off Cellular Data. On an Android phone, go to Settings, then Mobile Network, and toggle off Mobile Data. You can also enable Airplane Mode, which disables all wireless connections at once. With both cellular and data off, you cannot make calls, send texts, or use data, but you also will not incur any roaming charges.

If you need to stay reachable while traveling, purchase a roaming plan from your carrier before you leave. Most carriers offer day passes, weekly passes, or monthly passes for specific countries or regions. AT&T, Verizon, T-Mobile, and other major carriers all offer these plans. A day pass typically costs $10 to $12 and includes unlimited calls, texts, and a set amount of data (usually 500 MB to 1 GB) for 24 hours. A monthly plan costs $60 to $100 and covers the entire month. These plans are far cheaper than pay-as-you-go roaming rates.

Another option is to purchase a local SIM card when you arrive at your destination. A local SIM gives you a phone number in that country and connects you to the local carrier at local rates. You will need an unlocked phone to use a local SIM. This option works well if you are staying for more than a few days, because the cost of the SIM card and a local plan is often lower than a roaming plan from your US carrier.

What to do if you see unexpected roaming charges

If you see roaming charges on your bill that you did not expect, contact your carrier as soon as possible. Call the customer service number on your bill or visit your carrier's website to start a dispute. Most carriers allow you to dispute charges within 30 days of the bill date. When you contact them, have your bill in front of you and be ready to explain which charges you are disputing and why.

Some roaming charges can be reversed if you can show you did not authorize them or if they resulted from a carrier error. For example, if your phone connected to a roaming network without your knowledge and you had roaming disabled, the carrier may reverse the charges. If you were charged for data you did not use, the carrier may investigate and credit your account. However, if you knowingly used your phone while roaming without a plan, the carrier will likely not reverse the charges.

If the carrier refuses to reverse the charges and you believe the dispute is valid, you can file a complaint with the Federal Communications Commission (FCC). The FCC investigates complaints about billing disputes and can pressure carriers to resolve them. You can file a complaint on the FCC's website at fcc.gov/consumers.

Roaming plans and packages offered by major carriers

AT&T offers Passport, a monthly roaming plan that costs $60 to $100 depending on the country and includes unlimited calls, texts, and data. Verizon offers TravelPass, which charges $10 per day for unlimited calls, texts, and data in over 210 destinations, and you are only charged on days you use your phone. T-Mobile includes roaming in over 210 countries and destinations at no extra charge as part of its standard plans, though data speeds may be slower. Sprint (now part of T-Mobile) also includes international roaming at no extra charge.

If you travel frequently, compare these plans against the cost of purchasing a local SIM card or using a travel-specific phone plan from a company like Google Fi or Wise. Google Fi charges $10 per gigabyte of data and $0.20 per minute for calls in over 200 countries, with no monthly commitment. Wise (formerly TransferWise) offers a travel SIM that works in over 150 countries. These alternatives are often cheaper than roaming plans if you use data sparingly or travel to multiple countries.

Frequently Asked Questions

Can I turn off roaming to prevent charges?

Yes. On most phones, you can disable roaming in your settings. On iPhone, go to Settings > Cellular > Cellular Data Options > Roaming and toggle it off. On Android, go to Settings > Mobile Network > Roaming and toggle it off. With roaming disabled, your phone will not connect to other carriers' networks, so you will not incur roaming charges. However, you also will not have service in areas where only roaming networks are available.

Will I be charged if my phone automatically connects to a roaming network?

Yes, unless you have roaming disabled or a roaming plan in place. Your phone automatically connects to available networks without asking permission. If that network is a roaming network and you use your phone, you will be charged. This is why it is important to disable roaming before you travel or to purchase a roaming plan in advance.

How much does international roaming cost per minute?

Costs vary by country and carrier, but international roaming typically costs $1 to $3 per minute for calls, $0.50 to $2 per text, and $5 to $10 per megabyte for data without a plan. Some countries are more expensive than others. Roaming in Europe or Canada is usually cheaper than roaming in Asia or Africa. Check your carrier's website for rates specific to your destination.

Is there a way to use my phone abroad without roaming charges?

Yes. Connect to WiFi whenever possible — calls and texts sent over WiFi do not incur roaming charges. You can also purchase a local SIM card, use a travel-specific phone plan like Google Fi, or buy a roaming plan from your carrier before you leave. Airplane Mode also prevents all charges, but you will not be reachable.

Can roaming charges be removed from my bill?

Sometimes. If the charges resulted from a carrier error, unauthorized use, or a phone connecting to a roaming network without your knowledge, the carrier may reverse them. Contact your carrier within 30 days of the bill date to dispute the charges. If the carrier refuses, you can file a complaint with the FCC.
