US Mobile International Calling: Plans, $3 Add-On and Country Caps

US Mobile includes international calling from the US to 200+ countries on most of its plans, and on the rest it is a $3 a month add-on, as of October 2026. There is no per-minute charge and no overage: most countries are unlimited, and a short list has a monthly minute cap.

That makes US Mobile one of the cheapest ways to call abroad from a US phone. The catches are the capped countries, the Custom plan (which cannot add it) and the fact that none of this applies once you leave the US.

Does your US Mobile plan include international calling?

US Mobile's help article on calling and texting foreign numbers lists it plan by plan. As of October 2026:

Plan	International calling from the US	Networks
Unlimited Premium (monthly or annual)	Included	Warp, Light Speed, Dark Star
Unlimited Starter, annual	Included	All three
Unlimited Starter, monthly	$3 a month add-on	All three
Unlimited Flex	Included	All three
By-the-Gig	Included	All three
Light Plan, annual	$36 a year add-on	Dark Star and Light Speed only
Light Plan, monthly	$3 a month add-on	Dark Star and Light Speed only
Home Phone	Included	All three
Custom Plan	Not available	None

US Mobile says international calls and texts "don't incur any extra charges or overages." There is no pay-per-minute fallback either. If your plan does not include calling and you have not added it, you cannot use your line to call abroad.

Which countries have a monthly cap?

US Mobile's international calling page lists every destination with its allowance for calls to mobile numbers. Most say "Unlimited", including Mexico, India, the UK, the Philippines, Colombia and Pakistan. 23 destinations have a fixed number of minutes each month instead. The best-known ones, as of October 2026:

Destination	Minutes to mobiles each month
Israel	280
Kenya	228
Nigeria	209
Ghana	200
Switzerland	160
United Arab Emirates	158
Honduras	157
Sri Lanka	152
Guatemala	151
Haiti	70
Belgium	67
Morocco	38

Three rules sit around those numbers:

• No top-ups for capped countries. US Mobile says "we will not be offering additional minutes to limited-minute countries." Once you hit the cap, you wait for next month.
• Personal use only. The page says all international long distance calling "is only for personal use", and points to a Fair Use Policy.
• Landlines are treated differently. The table only lists mobile minutes. The same page says "You can call all destinations for unlimited minutes from a landline." It is not fully clear whether that means calling landline numbers or using US Mobile's Home Phone service, so check the page for your country if you mostly call landlines in a capped destination.

How much does a 10-minute call cost?

For the five countries in this guide, the plan math is simple: they are all unlimited. Here is what a 10-minute call costs on each option, with BoraPhone's rates at the time of writing (October 2026) for comparison. All prices are in US dollars.

Calling from the US to	US Mobile, plan with calling included	US Mobile, monthly Starter or Light	BoraPhone, 10 minutes
Mexico	$0	$3 a month add-on covers it	$1.10 to a mobile, $0.40 to a landline
India	$0	$3 a month add-on covers it	$1.11
United Kingdom	$0	$3 a month add-on covers it	$0.70 to a mobile, $0.40 to a landline
Philippines	$0	$3 a month add-on covers it	$6.50 to a mobile, $4.61 to a landline
Colombia	$0	$3 a month add-on covers it	$0.90

US Mobile has no per-minute rate to put in a third column, which is why the table has none.

Honest answer: when is US Mobile the better deal?

Almost always, if you are calling from your own US Mobile phone in the US. A $3 add-on covering every country on the list is hard to beat. Five minutes to a Philippine mobile on a pay-as-you-go service already costs more than that. If you call family in Manila, Mumbai or Bogotá every week, keep the calls on your US Mobile line.

A per-minute service only makes sense in a few gaps:

1. You are on the Custom plan, which cannot add international calling, and you call abroad only now and then.
2. You have used up a capped country. For example, once Belgium's 67 minutes are gone, you cannot buy more from US Mobile that month. Another 30 minutes to Belgium at a pay-as-you-go rate of $0.09 a minute would cost $2.70.
3. You are not at your phone. You want to call from a work laptop or a tablet, or someone else in the house needs to make the call.
4. You are abroad, where US Mobile's rules change (see the next section).

For those cases, BoraPhone lets you call landlines and mobiles in 180+ countries from a web browser, with no app or SIM. You buy credit from $5, see the rate before each call, and pay per minute, rounded up to the next full minute. The first call is free. It is cheap to places like Mexico, the UK, Belgium and Israel, and less so to the Philippines, Nigeria or Ghana, where a messaging app the other person already uses is often the cheaper choice. Rates for every country are on the international calling rate index.

How to turn on the International Calling add-on

This is only needed on a monthly Unlimited Starter line or a Light Plan line. Every other eligible plan already includes it. US Mobile's steps, as of October 2026:

1. Open your US Mobile dashboard (in the app or on the website) and select the line.
2. Under Line settings, choose Change Plan.
3. Pick the same plan you already have.
4. Select the International Calling add-on.
5. Complete checkout.

US Mobile's help article does not spell out how to remove the add-on. The plan change screen is where add-ons are chosen, so start there, and ask US Mobile support if you do not see the option.

On a Light Plan, check your network first. The add-on is only offered on Dark Star and Light Speed, not on Warp.

Dialing the number

Use the full international format: a plus sign (or 011 from the US), then the country code, then the number without its domestic leading 0.

• Mexico: +52 and the 10-digit number
• India: +91 and the 10-digit mobile number
• UK: +44 and the number without the first 0
• Philippines: +63 and the number without the first 0
• Colombia: +57 and the 10-digit number

What changes when you travel abroad

Everything above covers calls you make from inside the US. Once you are in another country, US Mobile treats you as roaming, and the rules come from your plan's roaming allowance or a roaming add-on, not from International Calling.

Points from US Mobile's international roaming help and plans page, as of October 2026:

• Roaming needs a plan that includes it or a roaming add-on, which you buy in the dashboard.
• Some plans include a roaming allowance. The plans page says Unlimited Premium comes with up to 20GB of roaming data, 200 minutes and 250 texts, and annual Unlimited Starter with 1GB, 200 minutes and 250 texts. Other plans need a roaming add-on.
• Roaming calls are limited. US Mobile says "you can only call to the country you're roaming in and back to the US", and that calls to a third country might not be supported.
• WiFi calling home is usually covered. Calls back to US numbers over WiFi are generally included, but calls to local foreign numbers over WiFi "may incur additional charges."
• Travel data eSIMs do not make calls. The FAQ on US Mobile's plans page says international calling "only works on our domestic (US) SIMs" and that its international data eSIMs "do not support calling."

So calling a restaurant in Lisbon while you are in Lisbon, or calling Germany while you are in Spain, is where you need a different tool.

Frequently asked questions

Does US Mobile charge for international calls?

Not per minute. International calling from the US is included on Unlimited Premium, annual Unlimited Starter, Unlimited Flex, By-the-Gig and Home Phone. On monthly Unlimited Starter and Light Plans it is a $3 a month add-on, as of October 2026, and the Custom Plan cannot add it.

Is there a limit on US Mobile international calling?

Most countries are unlimited for personal use. About two dozen have a monthly cap on calls to mobiles, such as Israel at 280 minutes, Nigeria at 209 and Morocco at 38. US Mobile does not sell extra minutes for capped countries.

How do I make an international call on my cellphone?

Dial a plus sign (hold 0 on most keypads) or 011, then the country code, then the local number without its leading 0. For example, a UK mobile 07700 900123 becomes +44 7700 900123. Saving contacts this way means they also work when you travel.

Can I call other countries while I am abroad with US Mobile?

Only in a limited way. Roaming calls can go to the country you are in and back to the US, and calls to a third country might not work. Calls to local numbers over WiFi may cost extra, and travel data eSIMs cannot make calls at all.
