The nitty gritty
Guinea-Bissau eSIM FAQs
No, our Guinea-Bissau eSIMs only deliver mobile data. For voice or SMS, you’ll need to use an app that works over data - WhatsApp, Skype, or other similar internet calling platforms.
Yes! Your Guinea-Bissau eSIM can be installed as early as 30 days before you travel. It won’t start until you touch down in Guinea-Bissau.
Installing beforehand means no setup stress on arrival, and it won’t use any data or days until you land.
If you get an activation warning on iPhone when installing before arriving, that’s normal - check our eSIM Troubleshooting Guide for details.
No - our Guinea-Bissau travel eSIMs are data-only, so they don’t come with a voice line or phone number. Any calls or texts must go through internet apps like WhatsApp, Telegram, or Viber.
Your eSIM will activate automatically when you arrive in Guinea-Bissau. We recommend installing your Guinea-Bissau Travel eSIM in advance (installation is different from activation).

Install Assistance: For help installing, consult our installation walkthrough. Still need help? Reach out and we’ll guide you step by step.

Yes it can. Nearly all ZenSim eSIMs support top ups inside the app. You can boost your data, add extra days, or attach a new country to the same eSIM from the Zen Garden in only a few steps.
Just log into the app, open the Zen Garden, and you’ll find the top up control ready to use.
Top up choices: The Guinea-Bissau top ups match the plans on our website, just with an extra 10% off.
If you're travelling longer than 30 days: You can purchase multiple top ups in advance. They only activate once the current plan finishes, so nothing overwrites your existing eSIM.
If your trip includes several destinations: Many of our eSIMs support multi country top ups. For example, you can add Dubai to a Europe eSIM and it will activate the moment you arrive without reinstalling anything.
Not exactly. Once your Guinea-Bissau eSIM is active, it’s tied to that country.
If you're visiting more than one place, our regional Travel eSIMs offer broader coverage so you can roam freely across multiple destinations.
You bet there is! Once you purchase an Guinea-Bissau eSIM you will be able to access your unique referral URL which you can share with your travel buds.
If they click the URL and purchase a plan they will save A$5 on their order and you will receive a A$5 voucher on your account which will be automatically applied on your next purchase (provided they are a new customer of course).
You can track your referrals and access your referral URL in the ZenSim app. Check out our terms for more info.
Only on unlimited plans, and only past 3GB in a single day - which is a generous amount, considering most travellers use less than 1GB daily.
If you do go past 3GB, your speed will be limited to 1Mbps until midnight, when it resets and you're back to full speed again.
Fixed-data plans (10GB, 20GB, etc.) don't have any daily throttling - you're free to use your data at whatever pace suits you until the plan's used up. We'll flag it before you run out, and topping up takes just a couple of taps in the ZenSim app.
It won't activate the moment you buy it - your Guinea-Bissau eSIM won't touch your data or days until you actually arrive, so there's no downside to installing it in advance.
As long as it's installed beforehand, it'll activate itself the second you touch down, and that's the moment your plan officially begins.
As for running out - your eSIM expires once your data or days are gone, whichever comes first (just the days, if you're on unlimited). Buy a 30-day plan and it'll run out 30 days after arrival in Guinea-Bissau, not 30 days after purchase.
Best way to find out is with our eSIM compatibility checker - just enter your phone details and it'll confirm whether it's compatible with our Guinea-Bissau eSIM and networks.
Not 100% sure, or getting an unexpected result? Contact us and we'll help sort it out. Worst case scenario, if your phone truly isn't compatible, our refund policy gives you a full refund - so there's no risk in trying.
Yep, that's precisely why we offer a 100% money back guarantee.
Whether it's a cancelled trip, an incompatible phone, or your travel plans simply shifting, you're covered either way.
You'll find the full breakdown in our refund policy, but the gist is: can't install it, can't use it, we'll refund it in full. Simple as that.

Discover the Untouched Beauty of the Bijagós Archipelago
The Bijagós Archipelago is a stunning collection of 88 islands off the coast of Guinea-Bissau, many of which remain uninhabited and teeming with wildlife. Declared a UNESCO Biosphere Reserve, these islands are home to rare saltwater hippos, sea turtles, and diverse bird species.

Whether you’re kayaking through mangroves, watching turtles nest on the shores, or simply soaking up the tranquillity, the Bijagós Archipelago is one of the most untouched gems of West Africa.

Bissau, the capital of Guinea-Bissau, is a fascinating mix of colonial history and vibrant local culture. The city’s markets, such as Bandim Market, offer a true taste of daily life, where stalls overflow with fresh seafood, colourful fabrics, and handcrafted goods. Walk through the historic streets to see remnants of Portuguese architecture, visit the Bissau Velho district, or stop by a local café to try Jollof rice and palm wine. For those interested in history, the Amílcar Cabral Mausoleum honours the revolutionary leader who played a key role in Guinea-Bissau’s independence.

Cantanhez Forest National Park, located in the south of the country, is a paradise for nature lovers. This biodiverse rainforest is home to chimpanzees, monkeys, and exotic bird species, making it an exciting destination for wildlife spotting. The park is also an important conservation area where local communities live in harmony with the environment. Visitors can take guided nature walks to explore lush jungle landscapes, meet the local Balanta people, and learn about traditional farming methods. If you love adventure and eco-tourism, Cantanhez Forest is a must-visit.
