Breaking Down Each Carrier's International Option
AT&T International Day Pass — $12/day
AT&T's International Day Pass charges $12 per day for each day you use your phone abroad. It gives you access to your existing US plan's data, calls, and texts in 210+ countries. The charge applies automatically the moment you use your phone — even for a single text message.
Verdict: Convenient but expensive. A 14-day trip costs $168 in day pass fees alone, on top of your regular monthly bill.
Verizon TravelPass — $10/day
Verizon's TravelPass works similarly to AT&T's day pass at $10 per day in 210+ countries. You get access to your existing plan's data allowance while abroad. Like AT&T, the charge triggers automatically on first use each day.
Verdict: Slightly cheaper than AT&T but still expensive for trips longer than a few days. A 14-day trip costs $140 in TravelPass fees.
T-Mobile International — Free 2G or $5/day for 4G
T-Mobile includes free international data in 215+ countries on most plans — but at 2G speeds, which are too slow for maps, streaming, or most apps. For usable 4G speeds, you pay $5 per day through their High-Speed Data Day Pass. Hotspot sharing is not included on international plans.
Verdict: The cheapest carrier option at $5/day for 4G, but still $70 for a 14-day trip and no hotspot. The free 2G tier is largely unusable for modern travel needs.
AloOui Travel eSIM — From $3.66
An AloOui eSIM gives you a local data plan in your destination country at a fixed price. Full 4G/5G speeds, hotspot sharing included, instant QR delivery by email, no ID required. Your US number stays active on your primary SIM for calls and texts.
Verdict: The best value option for any trip longer than 3 days. A 14-day Europe trip costs from $51.24 with AloOui vs $140 with Verizon or $168 with AT&T.
When Does a Carrier International Plan Make Sense?
In fairness, there are situations where sticking with your carrier is the right call:
- Trips of 1 to 2 days — the setup time for an eSIM may not be worth it for a single overnight trip
- Emergency use only — if you only need your phone for occasional calls and minimal data, a day pass may be acceptable
- Corporate accounts — some business plans include international coverage at no extra cost
For any trip of 3 days or more, a travel eSIM will almost always be cheaper.

Frequently Asked Questions
Is AloOui eSIM cheaper than AT&T's International Day Pass?
Yes, significantly. AT&T charges $12 per day. AloOui's Europe Lite plan costs $3.66 for 7 days — that's less than a third of a single AT&T day pass for an entire week of data.
Can I keep my US number while using AloOui abroad?
Yes. Your US number stays active on your primary SIM slot for calls and texts. AloOui handles data on a second eSIM slot. Both run simultaneously — you do not lose access to your US number.
Do I need to cancel my US carrier plan to use AloOui?
No. AloOui runs alongside your existing US carrier plan. You keep your US number and plan active — you simply disable data roaming on your US SIM and use AloOui for data while abroad.
Does T-Mobile's free international data actually work?
Technically yes, but at 2G speeds (typically 128 kbps), which is too slow for Google Maps, streaming, or most apps. It is sufficient for basic messaging only. For practical travel use, you need T-Mobile's $5/day 4G add-on or a travel eSIM.
How quickly do I receive my AloOui eSIM after purchase?
Instantly. Your QR code is delivered by email within seconds of purchase, 24 hours a day. No waiting, no store visit, no ID required.
