Public Mobile is a genuinely good deal for Canadians who stay in Canada. Telus-backed, reliable 5G coverage in urban areas, and some of the lowest plan prices among the major networks. But the moment you book a flight to anywhere beyond the US or Mexico, the picture changes fast. Public Mobile international roaming is, in practice, limited to North America. If you're heading to Europe, Asia, the Caribbean, or anywhere else on the globe, your Public Mobile SIM simply doesn't have a roaming option for you. No add-on to purchase, no workaround through the app. This guide explains exactly what Public Mobile does and doesn't cover for travel, how the US and Mexico plans work, and what your options are when you're heading somewhere that Public Mobile can't follow.
Public Mobile is a Telus owned flanker brand, positioned as the budget friendly alternative to the main Telus lineup. The trade off for lower monthly prices is a more limited feature set, and international roaming is one of the clearest examples of that trade off.
Public Mobile’s international coverage is currently restricted to the United States and Mexico only. There is no roaming add on available for Europe, Asia, the Middle East, Africa, South America, or any destination outside North America. This is not a pricing quirk or a temporarily unavailable feature. As of March 2026, Public Mobile has not indicated plans to expand beyond the US and Mexico for roaming coverage.
For US and Mexico travel, Public Mobile takes two approaches. The first is dedicated US roaming add ons, available in 15 day or 30 day bundles. These give you talk, text, and data in the United States on AT&T, Verizon, or T-Mobile’s networks. Coverage includes all 50 states plus Puerto Rico and the US Virgin Islands, though Alaska requires a VoLTE capable device for voice calling to work properly.
The second approach is CAN/US and CAN/US/MEX plans, which bundle cross border coverage directly into the monthly subscription. These plans use the same data allowance across all three countries, with no separate roaming add on required. If you are on a CAN/US/MEX plan and you fly to Cancun, your plan data simply works in Mexico through roaming partners Telcel and Movistar. No activation steps needed.
One important limitation is that Public Mobile cannot receive international SMS from outside Canada unless a roaming add on is active. For travellers who rely on two factor authentication via text message, such as banking apps, email logins, or government portals, this becomes a real issue when travelling outside North America. The SIM stays in your phone, but incoming SMS does not arrive. Planning around this is essential if you travel to non covered destinations frequently.
Here's how Public Mobile's current roaming and cross-border plan options break down (prices in CAD; verify current rates in the Public Mobile app or website before purchasing):
Public Mobile's pricing model is prepaid-style with monthly auto-renewal, and the CAN/US/MEX plans tend to be rebalanced seasonally. The carrier has historically adjusted data volumes and pricing ahead of spring and summer travel seasons. Check the Public Mobile website or app for the current plan lineup before committing.
Step 1: Check your plan type. If you're already on a CAN/US or CAN/US/MEX plan, no activation is needed. Your plan data simply works across the border. If you're on a Canada-only plan, you'll need to either purchase a roaming add-on or switch to a CAN/US plan before travel.
Step 2: Purchase a roaming add-on if required. Log into your Public Mobile account through the app or website. Navigate to Subscriptions & Add-Ons and select the US roaming add-on in your preferred duration. Do this before you cross the border to avoid any gap.
Step 3: Enable data roaming on your device. On iPhone: Settings, Mobile Data, Mobile Data Options, enable Data Roaming. On Android: Settings, Connections, Mobile Networks, toggle Data Roaming on. This device-level setting is separate from your account configuration.
Step 4: Cross the border and connect. Your phone will automatically connect to AT&T, Verizon, or T-Mobile when you're in the US. If automatic network selection fails, go to Settings and manually select from the available networks. Tip: if AT&T is having connectivity issues in a specific area, manually switching to T-Mobile or Verizon often resolves it immediately.
Step 5: Monitor data usage. Your data draws from the same shared pool as your Canadian usage on CAN/US plans. Heavy US usage can deplete your monthly allowance faster than expected. The Public Mobile app shows real-time usage and remaining balance.
The straightforward answer is: anywhere outside the US and Mexico. That's a long list. Europe, the UK, Japan, South Korea, Thailand, Australia, the Caribbean, Central America, South America, India, the Middle East. Public Mobile has no roaming solution for any of these destinations as of March 2026.
Even within North America, the shared data pool can be a constraint. If you're on a 20GB or 30GB CAN/US/MEX plan and you spend three weeks in Mexico, your Canadian data budget takes a hit that affects the rest of your billing cycle. Heavy users on Mexico trips sometimes find themselves running short on data when they return home.
The two-factor authentication issue is also significant and catches many people off guard. Your Public Mobile number simply cannot receive SMS from international senders outside North America when you're travelling in uncovered regions. Banking apps, email recovery, government logins, travel booking platforms — many of these send verification codes via SMS. If you're abroad without a solution for your Canadian number, you may find yourself locked out of accounts at inconvenient moments. Switching to an authenticator app like Google Authenticator or 1Password removes this dependency entirely, which is good practice regardless of your carrier.
Public Mobile is an excellent carrier for everyday Canadian use. But international travel beyond North America exposes its fundamental limitation: there is simply no product to sell you when you're heading to London, Tokyo, Bangkok, or anywhere outside the US and Mexico. That's not a criticism of Public Mobile's pricing — it's an honest reflection of how budget carrier economics work. Lower monthly bills come with narrower roaming agreements.
The practical solution is an eSIM loaded for your destination, installed before you board. A TurkSIM eSIM for Europe, for example, covers 30+ countries with a single data plan. Your Public Mobile physical SIM stays in the phone in slot one, handling any incoming Canadian calls or SMS that manage to reach you (banking OTPs sent domestically will still arrive if your Canadian number is reachable). The eSIM handles all your data abroad.
This dual-SIM setup is particularly useful for Public Mobile users who rely on their Canadian number for 2FA. Keep the SIM in the phone, switch to an authenticator app for any service that allows it, and use the eSIM for data. You stay connected to the services you need and connected to your destination's networks at local rates.
The other reality is cost. If you're a Canadian on a budget carrier like Public Mobile, you're already making cost-conscious decisions about your phone plan. Paying for a dedicated destination eSIM only for the duration of your trip — rather than upgrading your whole plan or buying a roaming add-on that doesn't exist — fits that same cost-conscious logic. Pay for what you need, when you need it. No ongoing charges, no plan switching headaches.
No. As of March 2026, Public Mobile's international roaming is limited to the United States and Mexico. There is no roaming add-on available for Europe, Asia, Australia, or any destination outside North America. If you're travelling to one of these destinations, you'll need an alternative like a travel eSIM.
Public Mobile uses AT&T, Verizon, and T-Mobile for US roaming coverage. All 50 states are covered, including Puerto Rico and the US Virgin Islands. For roaming in Alaska specifically, you'll need a VoLTE-capable device for voice calling to function properly.
Public Mobile's CAN/US/MEX plans roam on Telcel and Movistar in Mexico. Both are major national carriers with broad coverage across urban areas and popular tourist destinations. If you're in a rural area and experiencing connectivity issues, manually selecting between Telcel and Movistar in your network settings often helps.
Not reliably. Public Mobile doesn't offer roaming services outside North America, which means your SIM has no active connection in European countries. SMS sent to your Canadian number from international senders may not arrive. Switching to an authenticator app for 2FA before your trip removes this dependency, and using a TurkSIM eSIM for data keeps you connected without needing to change your Public Mobile plan.
Yes, if your phone supports dual SIM. Keep your Public Mobile SIM in the physical SIM slot and install your TurkSIM eSIM as the second line. Set the eSIM as your data connection and leave the Public Mobile SIM active for calls and SMS. Your Canadian number stays reachable for any incoming SMS or calls, while your data runs through the eSIM at destination rates.
Log into your Public Mobile account via the app or website and go to Subscriptions & Add-Ons. Purchase the US roaming add-on in either 15-day or 30-day duration before you travel. Then enable Data Roaming on your device (Settings, Mobile Data, Mobile Data Options on iPhone; Settings, Connections, Mobile Networks on Android). Your phone will connect to AT&T, Verizon, or T-Mobile automatically when you cross the border.
Yes. Public Mobile uses monthly auto-renewal without contracts, so you can switch to a CAN/US/MEX plan before a Mexico trip and switch back to a lower-cost Canada-only plan when you return. The data pool on CAN/US/MEX plans is shared across all three countries, so heavy usage during your trip will reduce your Canadian allowance for the rest of the billing cycle. Factor that into your planning.
