Your carrier's roaming rate in Mauritania
| Carrier | Plan | Daily Rate | 7-Day Cost |
|---|---|---|---|
| Vodafone | Roaming Passport | £6/day | £42 |
| EE | Roam Abroad | £6/day | £42 |
| AT&T | International Day Pass | $10/day | $70 |
| Verizon | TravelPass | $10/day | $70 |
Vodafone Roaming Passport
Vodafone roaming at £6/day in Mauritania counts against your home plan's data allowance. Subscribers on lower-tier plans with less than 5GB/month hit the fair-use cap faster abroad.
EE Roam Abroad
Voicemail retrieval on EE in Mauritania is treated as an inbound call and can trigger the £6/day roaming pass on a day you hadn't planned to use data. Divert voicemail to a free app before departure.
AT&T International Day Pass
AT&T routes through Mauritel in Mauritania at $10/day — the same network a $2.00/GB eSIM uses.
Verizon TravelPass
Verizon caps high-speed data at a daily threshold before throttling in Mauritania. Once throttled, the $10/day charge continues. An eSIM at $2.00/GB delivers full-speed data up to the plan's GB ceiling with no hidden throttle.

Real savings scenarios for Mauritania
Solo traveler
Break-even point for a solo Mauritania trip: day one. AT&T charges $10 on the first calendar day. A 15GB eSIM at $30 is already cheaper than two AT&T days. By day 10, the eSIM has saved $70 total. There is no trip length at which AT&T roaming costs less than a travel eSIM for Mauritania.
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 Mauritania: $400. Four eSIMs at $30 each: $120. Per-person savings: $70. All eight data connections (4 carrier, 4 eSIM) route through Mauritel's 4G LTE towers.
Business trip
A 1-hour Zoom call in Mauritania 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 13GB eSIM at $26: 450 MB is a fraction of the plan. Business travelers average 2-3 video calls per day in Mauritania. The eSIM handles all of them within the same $26 fixed cost.
Long-stay and digital nomads
Per-hour data cost in Mauritania at different trip lengths: 5-day trip: AT&T = $0.63/waking hour, eSIM = $0.20/waking hour. 14-day trip: AT&T = $0.63/waking hour, eSIM = $0.19/waking hour. 30-day stay: AT&T = $0.63/waking hour, eSIM = $0.38/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 Mauritania is one stop on a multi-destination travel year: AT&T charges $10/day in every country. eSIM prices vary by destination. For Mauritania alone: $100 (AT&T) vs $30 (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 Mauritania. Local prepaid SIMs run $10-$30/month but require in-person purchase and passport registration. A travel eSIM on Mauritel at $120 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 Mauritania at 10 days each = 40 days of roaming. AT&T: $400/year. Four eSIMs: $120/year. Annual savings: $280 per employee. A company with 10 traveling employees saves $2800/year.
Data usage savings
Heavy data users — streaming, video calls, tethering — consume 3-5 GB/day. Over 10 days in Mauritania: 40 GB. AT&T: $100 (same flat fee; heavy users get the best per-GB value from day passes). eSIM on Mauritel: $80 at $2/GB. Even heavy users save with the eSIM. AT&T's day pass reaches cost parity only if the eSIM's per-GB rate exceeded $2.50/GB — and Mauritania eSIMs start at $2/GB.
Couples trip savings
A couple on AT&T traveling to Mauritania for 10 days: 2 lines x $10/day x 10 = $200. Two 15GB eSIMs: $60. Savings: $140. Both partners keep their US numbers active via WiFi Calling. Each eSIM connects independently to Mauritel's 4G LTE towers. No hotspot coordination required — each phone has its own data.
UK carrier comparison
Vodafone Roaming Passport charges GBP6/day in Mauritania. Over 10 days: GBP60 (approximately $76 USD at current exchange rates). A 15GB eSIM on Mauritel: $30 (USD). Savings in USD terms: roughly $30. Both options connect to Mauritel's 4G LTE towers in Mauritania.
Our verdict
Against AT&T: $70 saved (70%). Against Verizon: $70 saved. Against T-Mobile high-speed: $120 saved. Against T-Mobile free tier: $0 carrier cost but 256 Kbps speed renders maps, ride-hailing, and video calls unusable. A 15GB eSIM at $30 delivers full 4G LTE on Mauritel for less than any paid roaming option.

Frequently asked questions
- How much does AT&T roaming cost for 10 days in Mauritania?

- Is a travel eSIM cheaper than Verizon TravelPass in Mauritania?

- Can a family share one eSIM in Mauritania?
- One eSIM stays in one phone, but most eSIM plans allow tethering (personal hotspot). A family of 4 can share a single 10-20GB eSIM through one phone's hotspot instead of paying $10/day per person for carrier roaming.
- Does T-Mobile free data work in Mauritania?
- T-Mobile Magenta includes free data in Mauritania, 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 Mauritania?
- A 30-day eSIM for Mauritania 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 Mauritania?
- Vodafone and EE charge £6/day for roaming in Mauritania 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 Mauritania?
- A family of four on AT&T in Mauritania pays $40/day ($10/day per line x 4). Over a week that reaches $280. The same family shares one travel eSIM on Mauritel starting at $2/GB — 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 Mauritania?
- No. At 256 Kbps, T-Mobile's free international tier in Mauritania 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 Mauritel at $2/GB gives you real speeds without the daily fee.
- How is my roaming bill calculated in Mauritania?
- At 3 days in Mauritania: AT&T costs $30, eSIM costs $2/GB. At 7 days: AT&T $70, eSIM same $2/GB. 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.
- Is a travel eSIM more secure than using public WiFi in Mauritania?
- Yes. A travel eSIM on Mauritel's 4G LTE cellular network in Mauritania is a direct encrypted connection between your device and the tower — no shared network, no unauthorized interception point. Public WiFi at hotels, cafés, and airports is a shared network that other users on the same access point can monitor without a VPN. AT&T International Day Pass at $10/day uses the same secure cellular infrastructure as the eSIM. At $2/GB, the eSIM provides equivalent cellular-layer security at a fraction of the roaming cost. For banking and sensitive logins in Mauritania, cellular data is more secure than public WiFi. Rates checked June 2026.
- Does my phone automatically connect to roaming in Mauritania?
- Yes, if data roaming is enabled. Your phone latches onto Mauritel or another Mauritania carrier the moment the plane lands and your carrier bills at roaming rates — $10/day with a plan, or $2.05/MB without one. Disable data roaming on your home SIM before boarding. A pre-installed travel eSIM can be set to activate on arrival without triggering home carrier charges.
