Top Pick
Why our #1-ranked provider stands out.
HelloRoam earns our 2026 top pick on three concrete advantages backed by 90 days of side-by-side testing.
The per-GB pricing is the most competitive we measured: plans from $0.29/GB for large bundles, with typical 5-10GB plans at $1.40-$1.90/GB across 210+ countries as of May 2026. Tier-1 carrier partnerships mean the eSIM connects directly to local networks, providing 4G LTE and 5G coverage in supported markets.
HelloRoam also includes hotspot, tethering, and 5G at no extra charge on every plan. Holafly caps hotspot at 500 MB per day. Older MVNOs block tethering entirely. For travelers who pair a laptop with their phone on the road, the difference is hours of usable connectivity per day.

Common Questions
Frequently asked.
01What is an eSIM and how does it work for travel?
An eSIM is a digital SIM card built into your phone. Instead of buying a physical SIM card at an airport kiosk, you download an eSIM plan before your trip. Scan a QR code, activate the plan, and connect to a local carrier network the moment you land. No SIM swap, no store visit, no roaming charges.
02Which eSIM provider offers the lowest prices in 2026?
HelloRoam offers the lowest per-GB pricing in the market starting from $0.29/GB for large bundles across 185 countries as of May 2026. Nomad offers the cheapest absolute prices in Southeast Asia. Holafly offers the best value for heavy data users with unlimited daily plans starting at $2.50/day.
03Do I need to unlock my phone to use a travel eSIM?
Your phone must be carrier-unlocked to use a travel eSIM. Most phones purchased directly from Apple, Samsung, or Google are unlocked by default. Phones purchased through a carrier (AT&T, Verizon, T-Mobile) may be locked. Check Settings > General > About on iPhone or Settings > About Phone on Android.
04Can I use my phone number while using a travel eSIM?
Yes. A travel eSIM uses your phone's second SIM slot for data while your primary SIM keeps your home number active for calls and texts. You use the travel eSIM for data — maps, messaging apps, and browsing — and your home SIM for calls. Most modern phones support dual SIM with one physical and one eSIM active at the same time.
05How do I install an eSIM on my iPhone?
Installation takes under 90 seconds on any eSIM-compatible iPhone (XS 2018 or newer). Go to Settings, select Cellular, tap Add Cellular Plan, and scan the QR code from your provider. Label the plan, then set it as the default data line when you arrive at your destination.
06Is a travel eSIM cheaper than international roaming?
Yes. International roaming from major US carriers costs $10-15 per day. A travel eSIM with 5GB of data costs $3.49-$9.49 for 7-30 days depending on the provider and destination. That is 70-95% cheaper than carrier roaming for a typical two-week trip. Travel eSIMs are prepaid — you pay a fixed price before your trip with no monthly subscription or recurring charges.
07What happens if I run out of data on my travel eSIM?
Most providers let you top up your plan through their app or website without buying a new eSIM. HelloRoam and Airalo both support in-app top-ups that activate within minutes. If your provider does not support top-ups, you can purchase and install a second eSIM plan alongside the first.
