Moving abroad for three months, six months, or longer puts you in a gray zone between tourist and local. Travel eSIM plans are designed for short trips. Local carrier plans require residency documents you might not have. What is the best eSIM strategy for expats and long-term travelers? The answer depends on how long you are staying, how much data you need, and whether you have local documentation.
The Expat Connectivity Spectrum
Short-Stay Expat (1-3 Months)
Situations: Work assignment, sabbatical, language school, extended vacation, visiting family
At this duration, you are too long for a standard 7-30 day travel eSIM but too short to justify the hassle of getting a local carrier plan. You fall into the gap that neither travel eSIM nor local carriers serve perfectly.
Medium-Stay Expat (3-6 Months)
Situations: Contract work, study abroad semester, snowbird relocation, digital nomad stint
At three to six months, a local carrier plan becomes economically worthwhile if you can get one. But eSIM providers are starting to offer plans specifically for this duration.
Long-Stay Expat (6-12+ Months)
Situations: Permanent relocation, long-term work visa, full-year study abroad
At this point, getting a local phone plan is almost always the best option. You likely have residency documentation, you need a local phone number for banks and services, and per-GB costs on local plans are dramatically cheaper.
Option 1: Stacking Travel eSIM Plans
How It Works
Buy a travel eSIM plan from [triposim.com/destinations](/destinations) for your first 30 days. When it runs out, buy another one. Repeat for the duration of your stay.
Pricing Reality
Travel eSIM plans are priced for tourists, which means higher per-GB costs than local plans:
- 10 GB / 30 days: approximately $15-30 depending on country
- Monthly cost for moderate use (30-50 GB): approximately $50-100
Over 6 months, stacking travel plans could cost $300-600 for data alone.
Pros
- No documentation required
- No contract or commitment
- Start immediately upon arrival
- Switch to a different provider or plan size anytime
- Keep your home phone number active on your primary eSIM
Cons
- More expensive per-GB than local plans
- Need to repurchase every 30 days
- No local phone number (data-only)
- May be throttled or deprioritized compared to local subscribers
Best For
Short-stay expats (1-3 months) who value convenience over cost, or expats in countries where getting a local SIM is bureaucratically difficult.
Option 2: Local Carrier eSIM Plan
How It Works
Visit a local carrier store or use their website to purchase a local eSIM plan. This gives you a local phone number and a local data plan at local rates.
Requirements (Vary by Country)
| Country | Documentation Needed | eSIM Available? |
|---|---|---|
| UAE | Emirates ID or passport | Yes (du, Etisalat) |
| Saudi Arabia | Iqama or visa | Yes (STC, Mobily, Zain) |
| UK | Passport (some accept any ID) | Yes (EE, Three, Vodafone) |
| Germany | Passport + local address | Yes (Telekom, Vodafone, O2) |
| Thailand | Passport | Yes (AIS, True, DTAC) |
| Japan | Residence card | Limited eSIM options |
| USA | Passport (prepaid), SSN (postpaid) | Yes (T-Mobile, AT&T, Verizon) |
Pricing Reality
Local plans are dramatically cheaper:
- Thailand: Unlimited data plans from $10-15/month
- Germany: 30 GB for $15-25/month
- UAE: 20 GB for $25-40/month
- USA: Unlimited for $25-50/month (prepaid MVNOs)
Over 6 months, a local plan could cost $60-300 total versus $300-600 for stacked travel eSIM.
Pros
- Much cheaper per-GB
- Local phone number (needed for banks, delivery apps, government services)
- Not deprioritized on the network
- Often includes voice minutes and SMS
- Better customer support in local language
Cons
- Requires documentation (passport, residence permit, local address)
- May require visiting a physical store
- Contract terms or minimum commitment in some cases
- Porting your number later can be complicated
- Setup is more complex than scanning a travel eSIM QR code
Best For
Medium and long-stay expats (3+ months) who have local documentation and need a local phone number.
Option 3: Hybrid Approach (Recommended for Most Expats)
How It Works
Use a dual-eSIM or eSIM + physical SIM setup:
eSIM Profile 1: Your home carrier (keep your home number active for 2FA, banking, and family calls) eSIM Profile 2 (or physical SIM): Local carrier plan for daily data and a local number
Setup Steps
- Before departure, convert your home carrier to eSIM if it is still on physical SIM
- Arrive in your new country
- Use a travel eSIM from TripoSIM for the first few days while you settle in (browse plans at [triposim.com/destinations](/destinations))
- Visit a local carrier store within your first week
- Get a local eSIM or physical SIM plan
- Install the local plan alongside your home carrier eSIM
- Set the local plan as your default data line
- Keep your home carrier active but set it to "voice and SMS only" to avoid roaming data charges
Pros
- Best of both worlds: cheap local data + home number accessibility
- Local phone number for everyday use
- Home number stays active for important verification codes and family calls
- Can remove the travel eSIM once the local plan is active
Cons
- Requires managing two active lines
- Home carrier may charge a minimum monthly fee even when not using data
- Some phone models handle dual active lines differently
Best For
Any expat who needs to keep their home phone number while living abroad. This is the most common and practical approach.
Country-Specific Expat eSIM Recommendations
UAE (Dubai, Abu Dhabi)
The UAE requires Emirates ID for postpaid plans. Tourists and new arrivals can get prepaid eSIM from du or Etisalat with just a passport. Etisalat offers visitor plans starting at 30 AED ($8) for 2 GB. For long stays, the cheapest approach is a du Freedom Plan (postpaid, requires Emirates ID) at 75 AED/month for 10 GB.
Thailand
Thailand is one of the easiest countries for expat connectivity. Walk into any AIS, True, or DTAC shop with your passport and buy a prepaid SIM or eSIM immediately. Unlimited data plans start at 299 THB ($9) per month. No registration hassle, no minimum stay required.
United Kingdom
UK carriers offer both pay-as-you-go and monthly rolling contracts with no minimum term. Three (now merged with Vodafone) offers unlimited data for £25/month. You need a UK address for delivery of a physical SIM, but eSIM can be activated online with a passport.
Japan
Japan is notoriously difficult for expat SIM cards. Most major carriers require a residence card (Zairyu Card). New arrivals can use travel eSIM for the first weeks until their residence card is issued. Check our Japan plans at [triposim.com/destinations](/destinations).
Data Needs Calculator for Expats
Expats use more data than tourists because they are living, not just visiting:
| Activity | Monthly Data |
|---|---|
| Remote work (email, documents, light video calls) | 20-40 GB |
| Remote work (heavy video calls, screen sharing) | 50-100 GB |
| Social media and messaging | 5-15 GB |
| Streaming (Netflix, YouTube, 2 hours/day) | 30-60 GB |
| Navigation and food delivery apps | 2-5 GB |
| Cloud backup (photos, files) | 5-20 GB |
A typical remote-working expat uses 50-100 GB per month. This is well beyond what most travel eSIM plans offer cost-effectively, making a local plan essential for medium and long-term stays.

Frequently Asked Questions
Can I keep my travel eSIM as a backup after getting a local plan? Yes. Most phones allow multiple installed eSIM profiles. Keep your travel eSIM installed but disabled. If your local plan has issues, you can re-enable the travel eSIM instantly (assuming it still has data and validity remaining).
Do I need a local phone number as an expat? In most countries, yes. You need a local number for: bank account verification, delivery apps (Uber, food delivery), government services, local friends and colleagues, apartment rental contacts, and emergency services. Travel eSIMs are data-only and do not provide a phone number.
What if I move between countries every 1-3 months as a digital nomad? For country-hoppers, stacking travel eSIM plans or using regional plans (Europe, Asia, Middle East) is more practical than getting a new local plan in each country. The per-GB premium is worth the convenience. Browse regional plans at [triposim.com/destinations](/destinations).
Can I port my home number to a VoIP service while abroad? Yes. Services like Google Voice (US numbers), Skype Number, or other VoIP providers can hold your home number while you use a local SIM for daily connectivity. This is cheaper than keeping a home carrier plan active at minimum monthly cost.
