Can two phones share one eSIM connection
Yes, through the phone's personal hotspot, but the daily ceiling is set by the provider, not by the phone. Airalo's help pages, read on 17 September 2026, state a hotspot is supported "as long as it is supported by your device and the network," and tethered data simply comes out of the plan's total allowance. Holafly's Europe eSIM page, read the same day, puts a hard number on it, 1 GB of data per day can be shared, no matter how large the underlying plan is.
That gap matters more than the sharing feature itself. A family sharing an Airalo eSIM can point every device at the same hotspot until the plan's total data runs out, whenever that happens to fall in the trip. The same family on a Holafly Europe plan is capped at 1 GB shared a day no matter how large the underlying plan is, because the daily cap sits below the plan total, not on top of it, and the leftover allowance for that day cannot be carried into the next one. See how a travel eSIM works for the install and activation steps behind both cases, since the sharing rule only kicks in once the eSIM is actually installed and connected.
What Airalo's one-device rule means for hotspot
Airalo's help page on transferring an eSIM is specific, "the Airalo eSIM can only be installed on one device. Once it has been installed, it cannot be transferred to another device." That is a hardware limit, not a sharing limit, the eSIM profile is tied to the phone that activated it because it is embedded rather than swappable like a physical SIM.
The same help page then points to hotspot as the workaround, saying a new device can connect by enabling a personal hotspot from the old one. So one phone holds the eSIM, and every other family member's phone, tablet, or laptop rides on that phone's hotspot. Because Airalo's tethering page describes no separate cap, the family's usable hotspot data is the plan's full data allowance, split by however many devices connect, which is also why picking a large enough plan up front matters more with Airalo than the hotspot toggle itself does.
Why Holafly's Europe eSIM caps sharing at 1 GB a day
Holafly's Europe page frames the 1 GB daily cap as a feature, "share 1 GB of data per day with family, friends, or fellow travelers." For a solo traveler who wants a backup hotspot for a laptop, that is plenty. For two or three people streaming maps and messages off one phone, 1 GB a day is thin, and it resets at midnight rather than rolling over.
The page also carries a caveat worth checking before buying, "some Holafly eSIMs support this feature. Before purchasing, check the destination description to see whether data sharing is allowed." The cap is not universal across every Holafly destination, so the number to confirm before a family trip is the one printed on that specific country's page, not the Europe page in general.
| Provider | Devices per eSIM | Hotspot allowed | Daily sharing cap |
|---|---|---|---|
| Airalo | One (locked after install) | Yes, device and network permitting | None stated, draws from full plan |
| Holafly (Europe eSIM) | One | Yes, on eligible destinations | 1 GB per day |
| Yesim | One | Yes, on most plans, enabled by default | None stated, draws from plan allowance |
How Yesim treats tethered data on a family trip
Yesim's own help page says tethering is "available on most Yesim plans, including those for Apple iOS and Android smartphones," turned on by default with no extra charge to enable it. Data used through the hotspot still counts against the plan's total allowance, the same model Airalo uses, rather than Holafly's separate daily ceiling.
The page adds one caveat, availability can depend on the local network operator and may be restricted in some situations, so the hotspot toggle is worth testing at the airport rather than assuming it works the moment the eSIM connects. For a family combining a phone eSIM with a separate travel router, how a travel eSIM works covers the device pairing steps, and travel insurance, what it covers is worth a read alongside any data plan since neither covers a lost or broken phone the same way, and a family trip raises the odds of one going missing.
At what family size does one eSIM stop making sense
For two people on a plan with no separate tethering cap, such as Airalo or Yesim, one eSIM plus hotspot is a genuine way to skip buying a second one, the ceiling is just the plan's total data, shared however the family splits it. For three or more people, or any plan that caps sharing the way Holafly's Europe eSIM does, separate eSIMs per device stop being a nice-to-have and become the only way to avoid running dry mid-afternoon.
A rough way to size it, add up expected daily use per device (maps and messages run light, video calls and streaming run heavy), and compare that total against the plan's daily hotspot budget. If the total clears the cap by early evening on more than one day of the trip, buy a second eSIM rather than rationing the first one.
- Two people, light use (maps, messages), one eSIM with hotspot usually covers the trip on a plan without a daily sharing cap
- Two people, one streaming heavily, check the plan's total data against the trip length before relying on hotspot alone
- Three or more people, or a plan capped at 1 GB shared a day, price separate eSIMs per device instead
- Any group adding a second phone mid-trip, confirm the eSIM's one-device install limit before assuming it can move
