“Unlimited” daily plans give full speed up to the daily allowance, then unlimited data at a reduced speed (fair-use policy).

For Guinea-Bissau, use the table below as a quick price and friction check. Miyaw starts at $6.18; local SIMs and home-carrier roaming can still make sense in specific cases.
Miyaw eSIM
Best for
Prepaid travel data from $6.18, bought before you fly and installed by QR/link.
Watch out for
Data-only: keep your home SIM on for calls, SMS and bank codes.
Local physical SIM
Best for
Long stays, heavy hotspot use, or when you specifically need a local phone number.
Watch out for
You may need a shop visit, passport/registration, airport queues, or a SIM tray swap in Guinea-Bissau.
Home-carrier roaming
Best for
Short emergency use when convenience matters more than cost.
Watch out for
Daily passes and pay-as-you-go roaming can cost far more; check your carrier before switching it on.
We do not invent reviews. Miyaw has not yet published an attributed customer review for Guinea-Bissau; when we can verify one from a real customer or public review source, we will add the name/source and date here.
After your profile is issued, Miyaw's quick-install flow hands it to the iOS/Android Add eSIM screen in about 10 seconds: the provider setup link or LPA activation link opens pre-filled, while QR and manual details stay available as fallbacks. Finish the OS prompts, then check the line name, mobile-data line and data roaming before you fly.
Required: Data Roaming ON for the Miyaw line
Travel eSIMs connect through partner networks, so mobile data will not work abroad unless Data Roaming is enabled on the Miyaw eSIM line. Keep Data Roaming off on your main SIM to avoid home-carrier roaming charges.
