Groups Need a Different Strategy
Solo travelers get one eSIM and they're done. Groups of 2-6 people have more options โ and the math changes depending on group size, budget, and how often you split up.

The Three Strategies
Strategy 1: Everyone Gets Their Own eSIM
Best for: Groups that split up during the day
| Group Size | Cost (Saily 5GB each) | Total |
|---|---|---|
| 2 people | $13 ร 2 | $26 |
| 3 people | $13 ร 3 | $39 |
| 4 people | $13 ร 4 | $52 |
| 6 people | $13 ร 6 | $78 |
Pros: Complete independence. Everyone has their own maps, translation, messaging. Cons: Most expensive option for large groups.
Strategy 2: One Hotspot + Everyone Else on WiFi
Best for: Budget groups that stay together
One person gets an unlimited or high-data eSIM with hotspot, everyone else connects to their personal hotspot.
| Plan | Cost | Covers |
|---|---|---|
| Airalo Unlimited โ | $18/week | Up to 5 devices |
Pros: Cheapest ($18 for the whole group). Cons: Everyone depends on one phone. Battery drain is severe (hotspot phone dies in 4-5 hours). Group must stay together.
Strategy 3: Mix โ Navigator + Budget Plans
Best for: Most groups (our recommendation)
One person gets a mid-range plan for navigation and translation. Others get minimal plans for messaging only.
| Role | Plan | Cost |
|---|---|---|
| Navigator | Airalo 5GB โ | $16 |
| Others (ร3) | Saily 1GB โ | $4 ร 3 = $12 |
| Total (4 people) | $28 |
Pros: Half the cost of individual plans. Everyone has basic connectivity for messages and emergencies. Cons: Only one person has "full" data for maps and translation.

| Strategy | 2 people | 4 people | 6 people |

| Mix (1 navigator + budget) | $20 | $28 | $36 |

The mix strategy scales best โ cheap for small groups, still affordable for large ones.

1. Designate a navigator. One person handles Google Maps for the group.
2. Create a LINE/WhatsApp group before the trip. Everyone can message even on 1GB.
3. Download offline maps on every phone โ no data needed for basic navigation.
4. Share restaurant finds via the group chat instead of everyone searching independently.
5. Carry a portable battery for the hotspot phone (if using Strategy 2).

When Pocket WiFi Beats eSIM for Groups
If your group has members with non-eSIM phones (iPhone X or older, budget Android), pocket WiFi is the only option that covers everyone. It also avoids the "navigator's phone dies" problem since it's a separate device.
Trade-off: $35-70/week, separate device to carry, 6-8 hour battery, must return at airport.
