mySIM24

mySIM24 is a German provider contributing over 6,000 plans across 203 destinations — effectively full coverage. Its strength isn't headline pricing but range: 27 distinct durations, the widest in our comparison alongside MiESIM.

That makes it particularly useful for trips that don't fit the standard 7, 15 or 30-day moulds. A twelve-day trip, a forty-five-day stay, an extended posting: where others force you to round up, here there's usually a plan that fits.

Its 3,000-plus unlimited plans are genuinely unlimited with declared reduced speed, not data buckets in disguise, and the per-day price starts at $0.55 — the best in our comparison on that measure.

mySIM24 doesn't publish whether its plans allow tethering or include 5G. Those fields show empty on its rows in our tables.

That isn't the same as saying it lacks them. It means the data file we receive doesn't carry those fields, so we'd rather leave them blank than guess. If sharing the connection with a laptop is part of your plan, confirm it on their site before buying.

It's a limitation of information, not of the product. But when you're choosing between two similarly priced plans, knowing that one allows hotspot and the other doesn't changes the decision — and here we don't have that.

It's worth considering if your trip lasts something other than 7, 15 or 30 days, and if you'd rather buy unlimited than calculate how much data you'll burn. On both counts it's among the strongest options we track.

On price per gigabyte it sits mid-table at $0.50/GB on its better travel-sized plans, well behind the aggressive discounters. For a short trip where you know consumption will be light, you'll likely find better value elsewhere.

It's also a reasonable choice if you specifically want a European company for invoicing or German-language support.
