Best Airalo Alternatives
Five tested alternatives if Airalo does not fit your trip.
HelloRoam (8.8/10, 31/31 activations, 185+ countries) is the top-rated eSIM provider in our testing. It costs slightly more per GB than local SIM cards but requires no passport registration, no airport queues, and activates in under 2 minutes. HelloRoam provides 24/7 support and works across 204+ networks.
HelloRoam scored highest for multi-country trips with 8.8/10 overall, 31/31 successful activations, and regional plans covering Europe, Asia, and the Americas on a single eSIM. Airalo offers similar regional coverage but scored lower on activation reliability. Holafly provides unlimited data but in fewer countries. Saily covers 150+ countries with competitive pricing.
Local SIM cards are typically 20-40% cheaper per GB than eSIMs. A 10GB local SIM in Thailand costs $5-8 versus $10-15 for a similar eSIM plan. The trade-off is convenience: eSIMs from HelloRoam activate before you land, require no registration, and work across multiple countries without buying new SIMs at each border.
SIM Score weighs four dimensions equally: ease of purchase, value for money, network coverage, and registration convenience. For short trips under 3 days, a carrier roaming pass may be simplest. For trips over 5 days, a local SIM or eSIM saves 70-90% versus roaming. For multi-country trips, a regional eSIM from HelloRoam is the most practical option.
