The USA in 2025: incredible cities, stunning national parks, but data roaming? That's the tricky part. Traditional carriers charge a lot, and surprise bills can mess up your trip. Good news: eSIM makes it simple. With GoMoWorld, you install one eSIM valid in 200+ destinations and buy data plans as you go. No reinstalling, everything happens in the app. Plans for the USA start at €3.99 for 7 days. In this guide, we'll show you how to avoid roaming fees and stay connected the smart way.

Without a local solution in the USA, your home carrier's roaming will likely hit you hard. In 2025, most European and international carriers treat the USA as a high-cost zone. You'll pay daily fees or per-MB charges that add up fast—especially if you're using maps, Uber, or checking routes on the highway. While some carriers offer 'roam like at home' in Europe, the USA usually costs extra. With GoMoWorld, you get predictable data from €3.99.

Here's what major carriers charge in 2025:

• Vodafone (UK/EU): $10/day for 500MB; unlimited calls/texts extra at $5/day. Overages: $15/100MB.
• EE (UK): £7.50/day for 500MB; global roaming £25 for 10 days with 5GB total.
• O2 (UK): £6/day for 125MB; zone pass £10 for 1GB over 7 days.
• AT&T (US, international visitors): $10/day for 1GB shared data.
• Orange (France): €25 for 10 days with 20GB; €0.05/MB after.

Pas de stress: These rates can hit $50/day easily with heavy use. Download the GoMoWorld app and skip the surprise bill.

The USA has solid mobile infrastructure in 2025. Three big operators cover most of the country, but coverage varies—cities get great 5G, rural areas might run on 4G. If you're in LA or Chicago ordering Ubers, you'll get super fast speeds. National parks or the Midwest? Expect 4G LTE. GoMoWorld eSIMs connect to these networks, so you stay online whether you're hailing a ride or driving cross-country. We use multi-network access for best coverage.
