Does Ultra Mobile work when I travel internationally?

Limited. Ultra Mobile is primarily a US-side product, and international roaming is not included on most plans. The $39, $49, and $59 plans include Ultra's "Mobile Without Borders" feature, which allows free roaming and unlimited calls/texts within Mexico and Canada (data caps apply). Outside North America, Ultra phones do not work on most foreign networks; you would need to swap to a local SIM or purchase international roaming separately. Ultra also does not provide Wi-Fi calling abroad on most plans, so even with a Ultra SIM in your phone, calling from a Paris hotel doesn't work without a local SIM or browser-based service.

How do I make an international call on Ultra Mobile?

Dial + followed by the country code and number (e.g. +44 20 7123 4567 for a London landline), or use 011 + country code + number for the legacy international dialing format. Both work from any Ultra Mobile phone within the US. Calls to Ultra's 80+ unlimited destinations are included free at the line types listed; calls outside that list bill per-minute against your account or eat your monthly $5-$10 International Calling Credit (on $39+ plans). To check whether a specific number qualifies as unlimited, look up the country and line type at ultramobile.com/international-calling before placing the call; landline-only or carrier-specific entries (like Pakistan's Zong Network) are easy to misread.

Why is my Algeria call not free if Algeria is on Ultra's unlimited list?

Because Algeria is listed as landline-only on Ultra's destination list, not landline-plus-mobile. The "80+ destinations" headline mixes country names without distinguishing line types, so a country can appear unlimited while only one of its line types qualifies. Algeria, Angola, Bhutan, Brunei, Northern Mariana Islands, and UAE are all landline-only on Ultra. Japan and Namibia are mobile-only. Pakistan is unlimited only to Zong Network numbers, not other Pakistani carriers. Before counting on "free," check the specific line type for your most-called number. Per-minute rates on the metered side run $0.02-$0.50/minute and consume your monthly International Calling Credit ($5 on $39 plan, $10 on $59 plan) before billing PayGo.

Can my family abroad use Ultra Mobile's plan to call my US number cheaply?

No. Ultra Mobile plans cover outbound calls from your US-based Ultra line to international destinations. They do not cover the reverse direction (someone abroad calling your US number). Family in India, Mexico, or anywhere else pays their home-country carrier's international rate to call your US number, with no benefit from your Ultra plan. For the reverse direction, they need a service like WorldDialer ($0.04/minute to US landlines from any browser), a calling card, or a US-inclusive plan on their home carrier (T-Mobile India equivalents, BSNL international packs). Ultra is a US-side product; the international calling benefit travels with the SIM, not with the called number.

Is Ultra Mobile the same company as Mint Mobile?

Both are owned by T-Mobile USA, which acquired their parent company Ka'ena Corporation in May 2024 for $1.35 billion. Both run as MVNOs on T-Mobile's 5G network with identical coverage to parent T-Mobile postpaid. They target different markets: Ultra Mobile is positioned for immigrant communities calling specific international corridors, with unlimited international calling bundled on every plan ($19-$59/month). Mint Mobile targets the general price-conscious US consumer who rarely calls abroad; Mint's plans start at $15/month with no international calling included (pay-per-minute, or $5/month add-on for unlimited to ~40 countries). Same network, same parent, different jobs. Ryan Reynolds remains a public face for Mint after the acquisition.

What Ultra Mobile International Calling Actually Costs in 2026

Ultra Mobile international calling includes unlimited talk and text to 80+ destinations on every paid plan, from $19 per month and up. The "80+ destinations" headline blurs the picture though — some countries get unlimited mobile and landline, some get only landlines, some get only one specific carrier's network. Here's the actual breakdown.

What Ultra Mobile actually charges for international calling

Ultra Mobile international calling costs nothing extra on top of the base plan — every paid tier from $19 to $59 per month includes unlimited talk and text to its 80+ unlimited destinations.

Plan | Single month | Unlimited 80+ destinations | Calling Credit

3GB | $19 | Included | None

8GB | $24 | Included | None

12GB | $29 | Included | None

24GB | $39 | Included | $5/month

Unlimited (40GB) | $49 | Included | $5/month

Unlimited+ (60GB) | $59 | Included | $10/month

That's a real value compared to Cricket, Metro by T-Mobile, or Boost — those carriers charge $5 to $15 extra per month for an international add-on on top of the base plan. Ultra bundles it.

The $39 plan and higher also include a monthly International Calling Credit ($5 or $10) for destinations that aren't on the unlimited 80+ list. Multi-month commitments — 3, 6, or 12 months prepaid — drop the per-month price up to roughly 50%, so the $19 single-month plan can run closer to $14 on a 12-month buy.

The "80+ destinations" math: destinations don't mean countries

Ultra Mobile's 80+ destinations isn't 80+ countries — it's a count that mixes landlines, mobile networks, and in some cases a single carrier's network within a country.

The actual line breakdown from Ultra's documented expansions:

Unlimited to both landlines and mobiles: India, Mexico, China, Brazil, Germany, South Korea, Italy, Ireland, Malaysia, Dominican Republic.
Unlimited to landlines only (mobile costs extra): Algeria, Angola, Bhutan, Brunei, Northern Mariana Islands, United Arab Emirates.
Unlimited to mobiles only (landline costs extra): Japan, Namibia.
Unlimited to one specific carrier within a country: Pakistan, where the unlimited tier covered only the Zong Network as recently as 2024.

The practical impact: if you call your aunt's mobile in Algeria, that call probably isn't free even though Algeria is "in the 80+." If you call a non-Zong number in Pakistan, same story. The country name on the destination list doesn't tell you which lines in that country are actually unlimited — you have to check the line type, and sometimes the carrier.

Ultra also updates the destination list periodically without notifying customers. A country that was unlimited last year may now be landline-only, or vice versa. The 80+ headline can grow to 90+ and shrink back without an email going out.

How to read the unlimited list before you switch

Before switching to Ultra Mobile, check the specific destination type for the specific country you call most — not just whether the country name appears on the unlimited list.

The practical checklist:

Pull up Ultra's destination page at ultramobile.com/international-calling.
Search for your country.
Note the line type next to it — Landline, Mobile, or both.
If your most-called number is the line type that's NOT included, your unlimited plan isn't unlimited for that call.
Check the rate checker for the per-minute cost on the metered line.

Per-minute rates aren't published in a clean public table. They vary destination-to-destination, with $0.02 to $0.50 per minute as the typical range based on third-party tracking. The $5 or $10 International Calling Credit on the $39 and $59 plans eats those metered charges up to its monthly cap — useful margin for "mostly unlimited plus a couple metered calls a month," not enough to cover a heavy metered user.

Ultra Mobile vs Lyca Mobile: the real decision

Ultra Mobile vs Lyca Mobile comes down to which specific country and line type your unlimited tier covers — both run on T-Mobile's network, both bundle international calling, and both target the same immigrant prepaid shopper.

Factor | Ultra Mobile | Lyca Mobile

Headline coverage | 80+ destinations unlimited | 100+ destinations unlimited

Entry plan | $19/mo (3GB) | ~$19/mo (similar data)

Network | T-Mobile MVNO | T-Mobile MVNO

Heritage | Univision Mobile (LatAm focus) | South Asian / European focus

Data at same price | Typically more, more hotspot | Typically less

The headline destination count (100 vs 80) reads like a Lyca win, but the same destinations-don't-mean-countries gotcha applies to both. Each carrier's list has its own line-type quirks.

Where the choice actually splits by community: Lyca's unlimited tier has historically been stronger for Eastern European, Bangladeshi, and Pakistani lines. Ultra's has been stronger for Latin American destinations — a legacy of its 2016 Univision Mobile acquisition — and for broader Asian mobile coverage at the same price. Data allowances at the same monthly price tend to favor Ultra; Lyca's $19 plan typically gives less high-speed data and less hotspot than Ultra's $19 plan.

The honest decision rule: name your top three most-called numbers, including the line type for each. Check each carrier's unlimited list for those specific lines. Pick the carrier that covers more of YOUR three than the other. Both are otherwise fine.

The T-Mobile family connection

Ultra Mobile is a T-Mobile prepaid brand — T-Mobile bought parent company Ka'ena Corporation in May 2024 for $1.35 billion, which also brought sister brand Mint Mobile into the family.

Both Ultra and Mint run on T-Mobile's 5G network, so coverage matches parent T-Mobile postpaid. Different positioning though: Ultra targets immigrant international callers; Mint targets the price-conscious general consumer who doesn't call abroad much. Mint's base plan has no included international calling — it's pay-per-minute, or a $5/month add-on for unlimited calling to about 40 countries. Same parent, different jobs.

When Ultra Mobile's international math doesn't favor you

Ultra Mobile international calling is the right pick if you call multiple specific lines in countries firmly on its unlimited list — and you make enough monthly calls to amortize the $19+ base plan. For everyone else, the math runs uneven.

Three scenarios where it goes sideways:

Occasional caller, US-side, outbound to international. $19 × 12 = $228 per year for the base plan. For 8 calls a year at 15 minutes each (120 minutes total), that's $28.50 per call amortized. A pay-per-minute calling service handles the same 120 minutes a year for $4.80 to $12. Ultra makes sense if you call home weekly. If you call a few times a year, pay-per-use beats the subscription.
Most-called number is on the metered list, not the unlimited list. If your aunt's mobile is in a country that's "landline only" on Ultra's destination list, your headline-free plan still produces metered charges. The $5 to $10 monthly International Calling Credit on the $39 and $59 plans covers a few of those, but a heavy metered-side user pays twice — base plan plus PayGo overage.
Family in your home country needs to call your US numbers back. Ultra is a US-side outbound product. Your parent or sibling abroad calling your US number — your US bank, your US school, your US employer — doesn't get any benefit from your Ultra plan. They're paying their home-country carrier's international rate, or trying to dial a 1-800 number that doesn't connect from abroad. WorldDialer runs in any browser at $0.04 per minute to US landlines from any internet connection — that's the answer for the reverse direction. No app, no subscription required, just open the browser.

Quick reference: Ultra Mobile international calling scenarios

Here's what common Ultra Mobile international calling scenarios actually cost in 2026.

Scenario | Ultra (3GB $19) | Ultra (24GB $39) | Alternative

30-min weekly call to India mobile from US | $0 (unlimited) | $0 (unlimited) | Ultra wins

10-min call to Algeria mobile (landline-only on list) | PayGo ~$0.30-$0.50/min | Eats Calling Credit | Talk360 ~$0.10

Your spouse traveling abroad, calling US bank | Roaming rates apply | Roaming rates apply | WorldDialer $0.04/min from any browser

Family in home country calling your US number | Not applicable | Not applicable | WorldDialer $0.04/min in browser

8 short calls per year to home country | $228/year base plan | $468/year base plan | Pay-per-minute ~$5-$20/year

The "Not applicable" rows aren't a typo. Ultra is a US-side product — it covers calls leaving your US line. The reverse-direction job, where someone abroad needs to call your US number, isn't on Ultra's product map and isn't supposed to be.

When the math doesn't favor Ultra Mobile

Ultra Mobile international calling works if your most-called numbers are firmly on the unlimited list, you call regularly, and you're choosing between Ultra and Lyca as a daily driver. For everyone else, the math runs uneven — destinations that look free but aren't, line-type gotchas in the fine print, and a base plan that costs the same whether you call ten times this month or zero.

Need to call a US number from abroad for $0.04 a minute instead? WorldDialer runs in your browser. No app, no subscription required, no plan to upgrade. Pay for the call, not the plan.
