If you are searching for the best pay as you go phone because you only make occasional calls, the best choice is usually not a locked prepaid handset with an expensive international add-on.
For most people who need to call abroad, the best setup is:
an unlocked smartphone
a cheap domestic PAYG or prepaid option for backup talk, text, and data
a separate international calling method that does not force a monthly contract
That is the biggest gap in most ranking pages right now. They compare handsets or generic prepaid plans, but they do not answer the real question: which setup keeps international calls cheap without trapping you in a bad phone plan?
Best option summary
For the strongest international-calling setup, these are the options that make the most sense:
Best overall for occasional international calls
Unlocked Android phone + Ultra Mobile PayGo + BubblyPhone
Why it works:
Ultra Mobile PayGo starts at $3/month and includes 100 minutes, 100 texts, and 100MB. After that, extra minutes are $0.03 each, texts are $0.01 each, and data is $0.03/MB, according to the official Ultra Mobile PayGo page.
Ultra also states that you can use your PayGo wallet balance for international calls.
BubblyPhone adds a browser-based international calling layer, which is often simpler than relying on carrier international features for every destination.
Unlocked iPhone + Tello Pay As You Go + BubblyPhone
Why it works:
Tello says its Pay As You Go credit can be used for domestic and international calls, text, data, and international roaming.
Tello currently lists domestic PAYG pricing at 1 cent/minute, 1 cent/SMS, and 2 cents/MB on its official Pay As You Go page.
Tello also notes that PAYG balance expires after 3 months unless the line has an active plan.
This setup fits people who want a familiar iPhone experience and do not mind topping up ahead of time.
Best if you already use Google products
Unlocked phone + Google Voice
Why it works:
Google Voice is still useful for U.S.-based users who already live inside the Google ecosystem.
But Google explicitly warns in its official help docs that outside the U.S., international calls use minutes from your mobile phone plan and your mobile carrier might charge extra roaming fees.
That means Google Voice is often better as a U.S.-based option than as a travel-safe PAYG international strategy.
Best if you want one plan instead of a PAYG-style stack
Monthly prepaid plan with international credit
This is where many buyers get confused.
For example, H2O Wireless says its monthly plans include $1.50 or $5.00 of international talk credit depending on the plan. But H2O also says on its official international rates page that Pay As You Go plans do not offer international calling.
That makes H2O an okay option for people who want one monthly prepaid plan, but not a true PAYG international-calling winner.
Why most “best pay as you go phone” pages miss the real problem
Most articles ranking for this keyword do one of two things:
they list cheap prepaid phones
they list prepaid monthly plans and call them PAYG
That is fine for domestic budget shoppers, but it is weak for international callers.
If you need to call family overseas, reach a bank from another country, talk to a supplier, or make occasional business calls abroad, the decision is not just about the phone.
It is about five things:
Is the phone unlocked?
Does it support eSIM or easy SIM switching?
What is the minimum domestic cost when you are not using it much?
How do international calls get billed?
Will the setup still work when you travel or move between Wi-Fi and mobile data?
That is why the best PAYG phone for international calling is usually an unlocked device with a cheap base plan, not a flashy prepaid bundle.
The phone itself: what actually matters
Best type of phone for most people
An unlocked Android phone with decent battery life, LTE or 5G support, and either eSIM or dual-SIM support is usually the smartest PAYG choice.
Why:
easier to move between domestic plans
easier to pair with browser or app-based calling tools
lower upfront cost than most iPhones
better fit for people who want a backup line or second travel line
Best type of phone for Apple users
If you strongly prefer iPhone, the best PAYG phone is usually an unlocked iPhone you already own or a recent unlocked iPhone with reliable browser performance.
The key point is not the Apple logo. It is the fact that the phone is unlocked and can handle Wi-Fi, browser-based calling, and eSIM if needed.
Worst fit for international calling
A locked carrier prepaid phone can still work for basic domestic use, but it is often the wrong move for international flexibility.
Common problems:
harder to switch plans
international features tied to one carrier’s rules
worse travel flexibility
more friction if you want to use browser calling or a second SIM
Use-case breakdown
Best for occasional personal calls abroad
Choose Ultra Mobile PayGo + BubblyPhone or Tello PAYG + BubblyPhone.
Why:
low commitment
you are not paying for unlimited international minutes you never use
easy to keep as a backup or secondary calling setup
Best for travelers trying to avoid surprise charges
Choose an unlocked phone and avoid relying on default carrier international routing.
Google Voice itself warns that when you are outside the U.S., your mobile carrier may still charge roaming depending on how the call is placed. If your goal is cost control, that is a risk.
A browser-based option is often easier to manage because you can use hotel Wi-Fi, airport Wi-Fi, or local data without layering a carrier international package on top.
A browser-based international calling layer is usually stronger than a bare prepaid phone plan.
Why:
easier to call from laptop or desktop
simpler for remote teams
cleaner if you need to reach landlines, offices, or customers
easier to separate personal mobile service from business calling
This is where BubblyPhone fits especially well. If you want a route-level example of what these savings look like in practice, our How to Call India from the US and How to Call Mexico from the US guides show the difference between carrier pricing and cheaper internet-based calling.
Best for someone who only wants one phone number and one bill
A prepaid monthly plan with included international credit is more convenient than true PAYG, but it usually sacrifices flexibility.
That tradeoff is fine if convenience matters more than the absolute lowest cost.
Cost comparison: how these setups actually differ
Instead of pretending every option uses the same billing model, it is more useful to compare how each one charges you.
Ultra Mobile PayGo
Base cost: $3/month
Includes: 100 minutes, 100 texts, 100MB
Extra domestic minutes: $0.03/min
International calls: paid from wallet balance
Best for: true low-cost standby service
Tello Pay As You Go
Top-up model: starts with credit purchase
Domestic calling: $0.01/min
Text: $0.01/SMS
Data: $0.02/MB
International calling: supported from PAYG credit
Watch-out: balance expires after 3 months without an active plan
H2O monthly prepaid plans
Monthly plans: $20 to $60 with small international talk credit
PAYG plan: not a real international-calling option for new customers
Best for: one-plan simplicity, not lowest-commitment international calling
Google Voice
Good for: U.S.-based users who already use Google Voice
International calls: billed at listed rates
Important caveat: Google says calls outside the U.S. may still involve your mobile plan and roaming charges
TextNow
International calling works by adding account credit
Per-minute charges come out of that balance
Better for: very casual app-based use
Less ideal for: polished business calling or people who want a cleaner browser-first workflow
Pros and cons of the strongest setup
Unlocked phone + cheap PAYG base + BubblyPhone
Pros
low fixed cost
no need to buy an oversized monthly plan
works well for occasional international calling
cleaner for personal and business use
easier to move between carriers and countries
Cons
slightly more setup than buying one carrier bundle
you may manage two services instead of one
depends on Wi-Fi or mobile data for browser-based calls
Best for personal use
The best personal-use setup is usually:
Unlocked Android phone + Ultra Mobile PayGo + BubblyPhone
This gives you:
a cheap domestic backup line
real PAYG behavior
an easy way to make international calls when you actually need them
no pressure to pay for a monthly international add-on
Best for business use
The best business-use setup is usually:
Unlocked iPhone or Android + domestic SIM for backup + BubblyPhone for outbound international calls
Why it wins:
better for calling actual mobile and landline numbers abroad
easier to use from a browser
better fit for remote teams, freelancers, and small businesses
avoids stuffing every calling use case into a consumer prepaid carrier plan
Best browser-based option
The best browser-based option is BubblyPhone.
That matters because a lot of people searching for a PAYG phone do not actually want another app or another contract. They want to make a call, pay for the minutes they use, and move on.
BubblyPhone fits that workflow better than most prepaid-carrier international add-ons because it is built around:
transparent per-minute pricing
browser-based calling
no forced monthly phone contract just to place occasional international calls
BubblyPhone is not trying to replace your domestic PAYG line.
It fits as the international calling layer on top of it.
That is the important distinction.
If your phone only needs to stay reachable in the U.S., a cheap base PAYG option can handle that. When you need to call abroad, call a landline, reach a bank, or contact someone in another country without signing up for a big international plan, BubblyPhone is the more practical tool.
It is especially strong for:
occasional callers
travelers
remote workers
freelancers
small teams
people who want international calling without another app-heavy workflow
What is the best pay as you go phone for international calls?
The best option is usually an unlocked smartphone, not a locked prepaid handset. For most people, an unlocked Android or iPhone paired with a cheap PAYG base plan and BubblyPhone is the strongest international-calling setup.
Is a pay as you go phone cheaper than a monthly plan for international calls?
Often yes, especially if you call abroad only sometimes. PAYG is strongest when you want low standby cost and do not want to pay for unlimited international minutes you rarely use.
Can I make international calls from a true PAYG carrier plan?
Sometimes, but not always. Ultra Mobile PayGo and Tello PAYG support international calling. H2O explicitly says its PAYG plans do not offer international calling.
Is Google Voice enough for international calls?
It can be useful inside the U.S., but Google warns that outside the U.S. your mobile carrier may still charge extra roaming fees depending on how the call is handled.
Do I need a special international phone?
No. You need an unlocked phone with reliable Wi-Fi or data access. For most users, that matters more than buying a specific “international phone.”
What if I only make one or two international calls per month?
That is exactly where a PAYG setup wins. A low-cost domestic base plan plus a separate per-minute international option usually beats a bigger monthly package.
What should I read next?
If this is your use case, the most relevant follow-ups are:
The best pay as you go phone for international calling is usually the unlocked phone that gives you the most flexibility, not the prepaid bundle with the loudest marketing.
If you want the shortest version:
buy unlocked
keep the domestic plan cheap
do not overpay for international add-ons you barely use
use a browser-based international calling option when that is the real job to be done
That is the strongest angle for this keyword, and it is also the most honest answer.
