EE Roam Abroad

AT&T International Day Pass
AT&T's $10/day pass in Guinea-Bissau draws from your existing home-plan data bucket. Customers on base-tier plans with 5GB/month find they exhaust home data faster when roaming counts against the same pool.

Real savings scenarios for Guinea-Bissau
Solo traveler
Break-even point for a solo Guinea-Bissau trip: day one. AT&T charges $10 on the first calendar day. A 20GB eSIM at $129.05 is already cheaper than two AT&T days. By day 10, the eSIM has saved $0 total. There is no trip length at which AT&T roaming costs less than a travel eSIM for Guinea-Bissau.
Family trip
Verizon TravelPass charges per line, not per account. A family of four pays $40/day ($10 x 4 lines). Over 10 days in Guinea-Bissau: $400. Four eSIMs at $129.05 each: $516.20. Per-person savings: $-29.05. All eight data connections (4 carrier, 4 eSIM) route through Orange GW's 4G LTE towers.
Business trip
A 1-hour Zoom call in Guinea-Bissau on AT&T pay-per-use (no plan): 450 MB at $2.05/MB = $922.50. On AT&T International Day Pass: $10 for the day, but the day pass charges even if you only took one call. On a 20GB eSIM at $129.05: 450 MB is a fraction of the plan. Business travelers average 2-3 video calls per day in Guinea-Bissau. The eSIM handles all of them within the same $129.05 fixed cost.
Long-stay and digital nomads
Per-hour data cost in Guinea-Bissau at different trip lengths: 5-day trip: AT&T = $0.63/waking hour, eSIM = $0.86/waking hour. 14-day trip: AT&T = $0.63/waking hour, eSIM = $0.54/waking hour. 30-day stay: AT&T = $0.63/waking hour, eSIM = $1.08/waking hour. (Assuming 16 waking hours/day.) AT&T's per-hour rate stays flat. The eSIM's per-hour rate drops as the plan spreads across more days.
Frequent traveler annual savings
If Guinea-Bissau is one stop on a multi-destination travel year: AT&T charges $10/day in every country. eSIM prices vary by destination. For Guinea-Bissau alone: $100 (AT&T) vs $129.05 (eSIM) per 10-day trip. Across 4 international trips averaging 10 days each, AT&T charges $400 in roaming alone. eSIMs for the same itineraries run 80-95% less per trip.
Extended stay economics
Extended stays over 30 days open a third option: local prepaid SIMs in Guinea-Bissau. Local prepaid SIMs run $10-$30/month but require in-person purchase and passport registration. A travel eSIM on Orange GW at $344.40 for 30 days eliminates the store visit. AT&T at $300/month is the most expensive option regardless of stay length. For stays over 60 days, a local SIM may beat the eSIM on per-GB price, but the eSIM avoids registration paperwork and works from day one.
Frequent flyer savings
Business travelers averaging 4 international trips per year: 4 trips to Guinea-Bissau at 10 days each = 40 days of roaming. AT&T: $400/year. Four eSIMs: $516.20/year. Annual savings: $-116.20 per employee. A company with 10 traveling employees saves $-1162/year.
Data usage savings
A traveler using Google Maps 3 hours/day in Guinea-Bissau consumes 24 MB/day in navigation data. Over 10 days: 240 MB (0.2 GB). AT&T charges $10/day regardless of how little data you use. An eSIM at $5.74/GB on Orange GW charges $1.38 for navigation alone. The eSIM's per-activity cost is a fraction of the per-day fee.
Couples trip savings
One partner on AT&T, one on Verizon, traveling together to Guinea-Bissau: AT&T line: $100. Verizon line: $100. Combined: $200. Two eSIMs on Orange GW: $258.10. Savings: $-58.10. Both partners disable carrier data roaming and keep their home SIMs active for calls only.
UK carrier comparison
Vodafone Roaming Passport charges GBP6/day in Guinea-Bissau. Over 10 days: GBP60 (approximately $76 USD at current exchange rates). A 20GB eSIM on Orange GW: $129.05 (USD). Savings in USD terms: roughly $-69.05. Both options connect to Orange GW's 4G LTE towers in Guinea-Bissau.
Our verdict
Against AT&T: $0 saved (0%). Against Verizon: $0 saved. Against T-Mobile high-speed: $20.95 saved. Against T-Mobile free tier: $0 carrier cost but 256 Kbps speed renders maps, ride-hailing, and video calls unusable. A 20GB eSIM at $129.05 delivers full 4G LTE on Orange GW for less than any paid roaming option.

- Can a family share one eSIM in Guinea-Bissau?

- Does T-Mobile free data work in Guinea-Bissau?
- T-Mobile Magenta includes free data in Guinea-Bissau, but speed is capped at 256 Kbps. That is too slow for Google Maps, video calls, or uploading photos. The high-speed add-on costs $15/day.
- How much does a 30-day eSIM cost for Guinea-Bissau?
- A 30-day eSIM for Guinea-Bissau depends on data volume. Metered plans (5-20GB) typically range from $8 to $35. Unlimited daily plans run $1-2/day. Both connect to the same local network as carrier roaming at a fraction of the cost.
- Do UK carriers charge for roaming in Guinea-Bissau?
- Vodafone and EE charge £6/day for roaming in Guinea-Bissau outside their EU free-roaming zone. A travel eSIM on the same local network costs a fraction of that weekly rate.
- How much does carrier roaming cost in Guinea-Bissau?
- A family of four on AT&T in Guinea-Bissau pays $40/day ($10/day per line x 4). Over a week that reaches $280. The same family shares one travel eSIM on Orange GW starting at $7.74 for 1GB — a single purchase covers all devices through tethering. Verizon charges the same per-line rate. T-Mobile includes free data at 256 Kbps, which cannot load a map.
- Is T-Mobile's free international data fast enough in Guinea-Bissau?
- No. At 256 Kbps, T-Mobile's free international tier in Guinea-Bissau cannot load a map tile in under 15 seconds. Video calling needs 2 Mbps minimum — eight times what T-Mobile provides for free. Their paid speed upgrade runs $15/day. A 4G LTE eSIM on Orange GW at $5.74/GB gives you real speeds without the daily fee.
- How is my roaming bill calculated in Guinea-Bissau?
- At 3 days in Guinea-Bissau: AT&T costs $30, eSIM costs 1GB for $7.74. At 7 days: AT&T $70, eSIM same 1GB for $7.74. At 14 days: AT&T $140, eSIM same fixed rate. The eSIM billing model is flat — the longer the trip, the wider the gap. T-Mobile free tier is $0 but too slow at 256 Kbps to be usable beyond text.
- Can I use my travel eSIM as a hotspot in Guinea-Bissau?
- Most travel eSIM plans in Guinea-Bissau permit tethering — your phone shares its Orange GW 4G LTE connection with laptops, tablets, and other devices. AT&T roaming at $10/day also supports hotspot use under the International Day Pass. The cost difference remains: a travel eSIM at $5.74/GB versus $70 for a 7-day AT&T pass. One check before purchase: verify your specific eSIM provider permits tethering, as a small number of budget plans restrict hotspot use. Rates checked June 2026.
- Can I add more data to my eSIM plan mid-trip in Guinea-Bissau?
- Yes, with most providers. If you exhaust your Guinea-Bissau data plan, you purchase an additional top-up through the provider's app — no new QR code required on most platforms. The top-up activates within minutes on Orange GW's 4G LTE network. AT&T International Day Pass works differently: data access continues from your home plan's allowance as long as the day pass is active at $10/day. With an eSIM at $5.74/GB, you pay only for data you actually use — buy a small plan and top up if needed rather than committing to a large carrier weekly bill upfront. Rates checked June 2026.
