Plans price from $3.50/GB, well under the country's own $5.74/GB tracked floor set by its 5GB plan. Its 204+ carrier partnerships and 63-language checkout carry real weight in a market where enrichment data documents very limited mobile infrastructure nationwide.
Dimension scores, 0-5 on our rubric

- Fixed plans from $3.50/GB across popular destinations
- Unlimited plans from $5 for short stays, scaling by duration

Holafly's $2.99/day unlimited rate carries the same 2GB daily volume threshold tracked for Guinea-Bissau before its fair-use throttle applies, and its 4.5/5 in our comparison matrix Pricing score trails only Nomad's 4.8/5. Guinea-Bissau's own unlimited tier tops out at $12.69 per day on the 30-day plan, so Holafly's flat rate still beats the country's longest tracked unlimited option.
Dimension scores, 0-5 on our rubric
Pros

- 160+ countries covered including all major destinations

Nomad's $3.00/GB rate is the lowest fixed floor across all five providers, well under Guinea-Bissau's own $5.74/GB tracked rate. Its email-only support window is the thinnest of the five, worth weighing against enrichment data's documented very limited mobile infrastructure nationwide.
Dimension scores, 0-5 on our rubric

Is it cheaper to buy a bigger eSIM data plan in Guinea-Bissau?
Is it cheaper to buy a bigger eSIM data plan in Guinea-Bissau?
Not always. This comparison's Guinea-Bissau data shows the 5GB plan at $5.74/GB actually beats both larger tiers: the 10GB plan costs $6.88/GB and the 20GB plan costs $6.45/GB. The 5GB tier is the cheapest per-gigabyte option tracked across all five plan sizes for this country.
Does a VPN work with a Guinea-Bissau eSIM?
Does a VPN work with a Guinea-Bissau eSIM?
Yes. Enrichment data lists Guinea-Bissau's VPN status as unrestricted nationwide, so a VPN app works alongside any of the five eSIM providers compared here. Saily bundles a NordVPN connection into every plan at no extra cost, an option worth weighing against a separately downloaded VPN app.
Does Guinea-Bissau have 5G eSIM coverage?
Does Guinea-Bissau have 5G eSIM coverage?
No. This comparison tracks only 4G for Guinea-Bissau, carried by Orange, the sole network type recorded across all five providers compared here. Enrichment data lists MTN GW as the only other local carrier, and separately documents very limited mobile infrastructure as a nationwide quirk worth planning around.

Yes. This comparison's Guinea-Bissau data includes a full 30-day unlimited tier, priced at $380.81, working out to $12.69 per day, an 18% discount off the plan's base per-day rate of $15.48. Holafly's $2.99/day flat unlimited rate still undercuts Guinea-Bissau's own longest tracked unlimited option by a wide margin.

Why is mobile coverage limited in Guinea-Bissau?
Enrichment data documents very limited mobile infrastructure as a confirmed nationwide quirk for Guinea-Bissau, tied to Orange's network reach as the only tracked eSIM carrier. Travelers should expect thinner signal in rural areas regardless of eSIM provider chosen, since this restriction applies at the network level rather than varying by plan.
