Orange, SFR, Free, Bouygues in Thailand & Vietnam: Roaming

In short: Orange and SFR sell a pass for Thailand and Vietnam, Bouygues Telecom sells a data-only pass, and Free includes both countries in a 35 GB allowance (5G+ plan) or under fair-use thresholds (Max plan); with no pass, one megabyte costs between 6.50 EUR and 18.48 EUR depending on the operator. The nasty surprise is the unit: these prices are per megabyte, not per gigabyte.

Everything below was read on the operators’ own pages and brochures on 7 November 2026 (Free brochure dated 21 July 2026). Conditions change: check the page cited before you leave. We sell eSIMs for Thailand and Vietnam, which is why a comparison with our own prices appears below; operator figures are quoted as the operators publish them.

Orange: four Pass Voyage, from 9.99 EUR to 49.99 EUR

Thailand and Vietnam are on the list of 75 internet destinations of the Pass Voyage, for Orange and Sosh customers, with no commitment. Orange page read on 7 November 2026.

• The four passes: unlimited internet for 3 days at 9.99 EUR; unlimited with 30 minutes and 50 SMS for 10 days at 29.99 EUR; 50 GB with 30 minutes and 50 SMS for 31 days at 34.99 EUR; unlimited with 2 h and 100 SMS for 31 days at 49.99 EUR. “Unlimited” is Orange’s wording, quoted as is.
• Duration: days are consecutive from the activation date, which you choose at checkout; Orange prefers the day before arrival. The pass can be renewed, not automatically, and is incompatible with Mobicarte.
• Hotspot: included “subject to available mobile internet credit”, so within the pass volume.
• On the ground: Orange’s FAQ says the pass works in Phuket or Bangkok to call, text and use the internet, “subject to the country’s mobile coverage”.
• Without a pass: 13.31 EUR per MB of internet, 2.90 EUR/min for a call made, 1.40 EUR/min for a call received, 0.28 EUR per SMS sent (same for Thailand, Vietnam and Laos).

The Free 5G+ plan (19.99 EUR a month) includes 35 GB a month in 117 destinations including Thailand and Vietnam, and the Free Max plan (29.99 EUR a month) includes internet in 140+ destinations under fair-use thresholds. Free brochure of 21 July 2026.

• 2 EUR plan: Thailand 6.50 EUR and Vietnam 7.50 EUR per MB, with the Voyage option.
• Fair-use thresholds: detailed on page 29 of the brochure; that is where the limit of “included” sits.

Roaming or travel eSIM: the maths

For a week in Thailand our eSIM costs $8.90, against 9.99 EUR for three days of Orange or 29.99 EUR for ten; but on Free 5G+ or Max roaming costs nothing extra and the money argument disappears. eSIM prices come from our catalog (Thailand, Vietnam) on 7 November 2026, in dollars as displayed; operator prices are in euros as published.

Need	French operator	Our eSIM
A week in Thailand	Orange 10 days: 29.99 EUR; SFR: 35 EUR (10 GB); Bouygues: 30 EUR (3 GB); Free 5G+: included (35 GB)	7 days: $8.90 (35 GB full speed, then 1 Mbps minimum)
Ten days in Thailand	Orange 10 days: 29.99 EUR	10 days: $11.90 (network’s unlimited promotion)
A month in Thailand	Orange 31 days: 34.99 EUR (50 GB); Bouygues: 35 EUR (10 GB)	30 days: $47.90 (unlimited data, full speed)
A week in Vietnam	Orange 10 days: 29.99 EUR; SFR: 35 EUR; Free 5G+: included	Local 7 days: $4.90 (15 GB); Viettel 7 days: $9.90 (35 GB)
Two weeks in Vietnam	Orange 31 days: 34.99 EUR	Viettel 15 days: $14.90 (75 GB); local 15 days: $5.90 (25 GB)

What you lose and what you gain, honestly:

• For a month in Thailand, Orange’s 34.99 EUR pass is cheaper than our $47.90 eSIM. It also includes 50 GB, 30 minutes and 50 SMS, whereas our 30-day plan has unlimited data at full speed.
• Keeping your number. Roaming keeps your French number for calls and SMS. A travel eSIM is a data line; the Thailand plan can receive calls and SMS but not make them. With a dual-SIM phone, keep your French SIM for bank codes and use the eSIM for data.
• Check your phone first. An eSIM needs a compatible, unlocked phone. Our Vietnam eSIM guide covers installation, and one eSIM for Thailand, Vietnam and Cambodia helps if you chain countries.
• US carriers? See our article on Verizon, AT&T and T-Mobile roaming.

How to avoid a bill shock

The safest rule is to activate a pass or switch off data roaming before you land. With no pass, a phone refreshing apps in the background burns megabytes at 6.50-18.48 EUR each.

1. Check your plan before leaving: Free 5G+ or Max, or a pass bought from Orange, SFR or Bouygues.
2. Pick the activation date: at Orange, the day before arrival; at Bouygues, the pass starts at first data use.
3. Turn off mobile data or data roaming when you only want Wi-Fi, and disable app refresh and automatic updates.
4. Watch the volume: the Bouygues (3 GB or 10 GB) and SFR (10 GB) passes run out fast with tethering; see our tethering article.

What this page does not cover

This page covers the offers of the four network operators above. It does not detail the low-cost brands (Sosh, RED, B&YOU), business plans or foreign operators, whose terms differ. In those cases, read your operator’s page and compare the price per day or per gigabyte with a travel eSIM.
