Looking for a Holafly alternative?

When people compare Holafly with other travel eSIMs, the real question is usually unlimited data versus a fixed data pack. Unlimited is simple, but if you mostly use maps, messaging and the odd search, a fixed plan sized to your trip often does the same job for less.

SoloSim lets you choose: fixed data packs for most destinations, and unlimited or day-pass plans where a destination offers them. Each plan shows its data, validity, network speed and any fair-usage limit before you pay.

SoloSim at a glance

• Single-country plans for 202 countries, plus regional and global bundles.
• Data from $0.01 per GB.
• Fixed-data plans, plus unlimited or day-pass plans where a destination offers them.
• Buy on the website or in the app for iPhone and Android.
• Live data balance, expiry and top-ups in the app.

What to compare before you choose

1. Price for your exact trip. Compare the same data and the same number of days for your destination, not headline prices.
2. Coverage for every stop. For multi-country trips, check the regional bundle includes every country on your route.
3. What happens when data runs out. Check whether you can top up the same eSIM, and whether unlimited plans slow down after heavy use.
4. Network and speed. Look at which networks and speeds (4G/5G) the plan uses in your destination.
5. Your phone supports eSIM. Make sure your phone is eSIM-compatible and not carrier-locked before you buy.

Questions

Does SoloSim have unlimited data eSIMs?

Where a destination has unlimited or day-pass plans, they're listed on that destination's page next to the fixed-data plans. Unlimited plans may slow down after heavy daily use; the fair-usage limit is shown on each plan.

How much data do I need for a trip?

As a rough guide: maps, messaging and light browsing use about 0.3–0.5 GB a day; social media and regular browsing about 1 GB a day; video calls, streaming or sharing your connection 2 GB or more a day. Multiply by the days of your trip and pick the plan just above that.

Can I keep my old eSIM and add SoloSim?

Yes. Most eSIM phones store several eSIMs at once. Install SoloSim alongside your other eSIMs and choose which one to use for mobile data in your phone's settings — nothing needs deleting.

Can I switch to SoloSim in the middle of a trip?

Yes. Buy a plan, install the eSIM over Wi-Fi or your current data, then set SoloSim as the line for mobile data and turn on data roaming for it. Any data left on your old eSIM stays there until it expires.

Will my phone number change?

No. SoloSim plans are for mobile data. Your usual SIM keeps your number for calls and texts, and WhatsApp and iMessage keep working with your normal number.
