Our recommendation
We scored all 6 published plans for Guinea-Bissau against a 7-day moderate traveler profile. The 5GB plan at $28.68 delivers the best balance of data size and per-GB value.
The Pick: 5GB at $28.68
#1 RecommendationThe 5GB plan costs $28.68 in the HelloRoam catalogue and connects to Orange's 4G LTE network. Per-GB rate: $5.74/GB. That is the only per-destination price feed this site holds, so it is the only destination price we quote.
On plan shape and our published rubric, HelloRoam is the best fit of the 5 providers we score for a trip this size. Its own published entry rate is $3.50/GB, and it rates 8.7/10.
Who this plan fits
The typical Guinea-Bissau visitor who needs reliable data for navigation, social media, and messaging over 7 days without paying for unused capacity.
Why this plan
Trip-length match
1.5GB per day over 7 days totals 11GB. The 5GB plan matches your data requirement. That buffer covers photo uploads, group chats, and the occasional video call.

Provider score breakdown
HelloRoam scores 22.3 of 25 across the 5 rubric dimensions for Guinea-Bissau. 180-day refund window on unactivated eSIMs, tied for the longest. Support in 63 languages, more than the other four combined. The main trade-off: regional multi-country bundles are not available yet.
Network routing
Orange is the single operator on the published Guinea-Bissau list. The dataset records operator names and capability labels for Guinea-Bissau and nothing else: no throughput figure, and no statement of which operator a handset settles on. Plan the tier by trip length, not by the operator count.
Plan recommendation by usage tier
Each tier maps to a specific plan and provider for Guinea-Bissau.
Light user
Maps + messagingLight travelers in Guinea-Bissau (maps, messaging, email) use 4GB over 7 days at 0.5GB/day. HelloRoam's 5GB plan at $28.68 ($5.74/GB) covers the trip, and a local 4G LTE network carries it. That price is from the Guinea-Bissau catalogue. On our tier match, HelloRoam takes Light at 86 out of 100. Its published entry rate is $3.50/GB. The trade-off: no regional bundles yet, so multi-country trips need one plan per country.
Moderate user
Social + browsingModerate travelers in Guinea-Bissau (social media, navigation, browsing) use 11GB over 7 days at 1.5GB/day. HelloRoam's 20GB plan at $129.05 ($6.45/GB) covers that, and a local 4G LTE network carries it. This is the most common traveler profile and the plan size we recommend to first-time visitors. Holafly takes the Moderate tier at 96 out of 100. The trade-off with Holafly: no per-GB tier, so light users pay for data they will not use.
Heavy user
Streaming + callsHeavy-use verdict for Guinea-Bissau: 21GB over 7 days at 3GB/day. Unlimited runs $15.48/day on the Guinea-Bissau catalogue. Commit to 30 days there and the rate drops to $12.69/day, 18% off. Holafly scores 96 out of 100 at this tier. Limitation: no per-GB tier, so light users pay for data they will not use.
Your Guinea-Bissau trip type, matched to a plan
Weekend, vacation, business, or backpacking. Each trip profile maps to a different plan.
Weekend (2-3 days)
A 2-3 day Guinea-Bissau weekend uses 5GB for moderate travelers. Grab the 5GB plan at $28.68 ($5.74/GB). Per-GB rates reward big bundles, but a weekend cannot use one. Smallest sufficient plan wins. Light weekend users (email and maps) fit the 1GB plan at $7.74.
Vacation (7-14 days)
A 10-day vacation in Guinea-Bissau hits 15GB at moderate use. Social photo sharing moves the day from the 0.5 GB light band to the 1.5 GB moderate one. HelloRoam's 20GB plan at $129.05 covers the trip, and a local 4G LTE network carries it. Vacationers who stream or video-call family can switch to unlimited at $15.48/day instead. Pre-download restaurant guides and city maps on WiFi to hold the day on the light band.
Business (3-7 days)
Business trip to Guinea-Bissau (5 days): 15GB on the published 3 GB heavy band, which is what video calls, email sync and ride-hailing add up to. Unlimited at $15.48/day is the safe pick for corporate travel. Total: $77.40 for 5 days on a local 4G LTE network.
Backpacking (10-30 days)
Backpacking through Guinea-Bissau (14+ days): 12GB at 0.8GB/day for maps, hostel apps, and messaging. The 20GB plan at $129.05 ($6.45/GB) fits budget travelers on a local 4G LTE network. Ultra-light backpackers (email and maps only) start with 1GB at $7.74. Rural stretches burn data on navigation alone, so download the maps while you still have WiFi.
Your Guinea-Bissau provider comparison
Which eSIM provider fits your Guinea-Bissau trip? The answer depends on your usage tier, trip length, and priorities. Airalo's case is breadth. Nobody else we score publishes 200 destinations, and nobody else sells a bundle that crosses borders on one eSIM. Against that: $4.50/GB to start, dearer than all four rivals, and 14 days to change your mind. Holafly sells one shape and sells it everywhere: unlimited daily, published from $2.99/day, with a 180-day refund window matching the longest here. It is cheapest per gigabyte past 1.5 GB a day and dearest below it, with no per-GB tier to fall back on. Pick Saily if privacy ranks above plan choice. Nord Security's VPN rides on every plan from $3.99/GB published, and the app does not sell your data. Saily publishes 200 destinations, behind only Airalo, and support is email in 1 language, with no round-the-clock hours. Nomad wins one thing outright, and it is the thing most buyers check first: $3.00/GB, the lowest published fixed rate of the 5. Everything else is thin. One plan shape, 200 destinations, a 30-day refund window, and support that is email in 2 languages, with no round-the-clock hours. HelloRoam runs on 204+ carrier partners across 186 destinations. Fixed plans start at $3.50/GB, second only to Nomad among fixed rates. The 180-day refund window on unactivated eSIMs is the longest here, tied with Holafly. HelloRoam support is live chat, WhatsApp and email in 63 languages, around the clock. Trade-off: no regional multi-country bundles yet, and Airalo publishes 14 more destinations.
Why the rubric leader finishes first
HelloRoam finishes first on our published rubric at 8.7 out of 10, and the margin is thin. HelloRoam wins support access outright, live chat, WhatsApp and email in 63 languages, around the clock. It ties the longest refund window at 180 days on an unactivated eSIM. Where it loses: Airalo publishes 200 destinations against 186, and Nomad publishes a cheaper fixed floor at $3.00/GB against $3.50/GB. Guinea-Bissau itself runs on a local 4G LTE network whoever you buy from.

Published daily bands for a 7-day trip
| Band | GB per day | 7-day total | What it covers |
|---|---|---|---|
| Light | 0.5 | 4 GB | Maps, messaging, boarding passes |
| Moderate | 1.5 | 11 GB | The above plus social feeds and browsing |
| Heavy | 3 | 21 GB | Streaming, video calls, laptop hotspot |
HelloRoam sizes a Guinea-Bissau plan against those three bands and nothing else. A 7-day trip runs 4 GB on the light band, 11 GB on the moderate one and 21 GB on the heavy one, so the gap between the cheapest and the safest tier is 17 GB of headroom. Pick the band your phone habits already sit in at home.
Your calibrated Guinea-Bissau data budget
Your Guinea-Bissau data budget depends on more than usage habits. Local conditions shift the number up or down. Adjusted daily estimate: 1.5GB/day (down from the 1.5GB baseline). Over 7 days: 11GB total on a local network. The 20GB plan at $129.05 ($6.45/GB) covers this adjusted budget.

Your questions, answered
What is the best eSIM plan for Guinea-Bissau in 2026?
The 5GB plan at $28.68 on a local network, a HelloRoam catalogue price. It covers 7 days of moderate use at $5.74/GB. 6 plans are available across 5 providers.
How do I choose between fixed and unlimited data for Guinea-Bissau?
Fixed data wins for trips under 9 days at moderate use. Unlimited at $15.48/day saves money if you use more than 3GB per day or stay longer than 9 days.
Which eSIM provider is best for Guinea-Bissau?
HelloRoam scores 22.3 of 25 for Guinea-Bissau across per-GB value, plan flexibility, buyer protection, support access, and destination reach, which is first of the five on this site's weighting. 180-day refund window on unactivated eSIMs, tied for the longest. Regional multi-country bundles are not available yet.
Can I switch plans mid-trip in Guinea-Bissau?
Yes. Buy a second eSIM through the provider app while in Guinea-Bissau. Most phones support 8+ eSIM profiles. Delete the expired plan to free a slot. You do not lose your home number.
Should I buy a Guinea-Bissau eSIM or a regional bundle?
A Guinea-Bissau-specific plan gives the best per-GB rate for single-country trips. Regional bundles only make sense if you visit 3+ countries in the same region.
How far in advance should I buy my Guinea-Bissau eSIM?
Buy 1 to 3 days before departure. Install the QR code over WiFi at home. The validity timer starts at first network connection in Guinea-Bissau, not at purchase. This gives you time to troubleshoot any installation issues before your flight.
Is the 5GB plan enough for streaming in Guinea-Bissau?
Streaming puts a traveler on the published 3 GB heavy band. Over 7 days that is 21GB. The 5GB plan falls short for daily streaming. Heavy streamers should consider 20GB or unlimited at $15.48/day.
What network does my Guinea-Bissau eSIM connect to?
Orange is the single operator on the published Guinea-Bissau list. The published list carries the 4G LTE capability label, and it does not record which operator a given handset selects. Save offline maps for Guinea-Bissau before you fly.
