Vietnam eSIM

Most flagship smartphones released since 2018-2019 support eSIM, including iPhone XS and newer, Google Pixel 3 and newer, and Samsung Galaxy S20 series and newer. Tablets, smartwatches and an increasing number of laptops also support eSIM. The fastest way to verify your specific device is to check Settings , if you see "Add eSIM" or "Add cellular plan" as an option, you're compatible.

eSIM compatibility is now standard across the high-end smartphone market and rapidly spreading into mid-range devices. Cellesim works with any unlocked, eSIM-capable device , no special configuration needed beyond scanning the QR code we send you.

How to verify eSIM support on your device

1. iPhone: Settings → Cellular → look for "Add eSIM" or "Add Cellular Plan". You can also dial *#06# , if you see an "EID" (32-digit number), your phone has eSIM hardware.
2. Android: Settings → Connections (or Network & Internet) → SIM Cards → look for "Download a SIM instead" or "Add eSIM".
3. EID check: most eSIM-capable Android phones show EID in Settings → About Phone → Status.

Tip: Even if your phone supports eSIM hardware, it must be unlocked (not carrier-locked) to use third-party eSIMs like Cellesim. Most phones bought outright are unlocked; phones from carrier instalment plans may require unlocking after the contract is paid off.

Almost every flagship smartphone released since 2019 supports eSIM, making it ideal for international travel. Compatible models include iPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer, plus a growing list of mid-range devices. If your phone has Settings → Cellular → "Add eSIM", you're ready to use a Cellesim plan abroad.

Travellers benefit most from eSIM because it eliminates the airport SIM-card queue, removes the need to swap your home SIM out, and lets you keep your usual phone number active for SMS verification. A Cellesim travel eSIM activates the moment you land , no shop visit required.

What to check before buying a travel eSIM

1. eSIM hardware: dial *#06# , if an EID number appears, you're compatible.
2. Carrier unlock status: phones bought on instalment plans may be locked to your home carrier. Most outright purchases are unlocked.
3. iOS version: iOS 12.1 or newer for full eSIM support.
4. Android version: Android 9 or newer typically supports eSIM, though it depends on the manufacturer.
5. Region-specific variants: some Samsung models sold in Hong Kong or China are dual physical SIM with no eSIM , verify your specific model number.

Travel-friendly phones that don't support eSIM

• iPhones older than XS (iPhone X, 8, 7, 6 series).
• Most budget Android phones (entry-level Samsung A series before A53, Xiaomi Redmi entry models).
• Older Huawei devices without Google Services.
• Region-specific dual physical SIM variants (verify model number).

Tip: if your current phone doesn't support eSIM but you travel often, an unlocked, mid-range eSIM-capable phone (e.g., Pixel 7a, iPhone SE 3, Samsung Galaxy A55) makes an excellent secondary travel device , pair it with a Cellesim plan and you have a full mobile internet kit for any destination.

Nej, internettet er åbent! Dette er en almindelig misforståelse. I modsætning til Kina har Vietnam ikke den "store firewall". Du kan frit få adgang til Google, Facebook, Instagram, WhatsApp, TikTok, og alle dine yndlingsapps uden at skulle bruge en VPN. Vores eSIM giver dig ubegrænset højhastighedsadgang til det åbne internet. 

 Denne specifikke plan er kun gyldig i Vietnam. Dette er det vigtigste spørgsmål for backpackere. Hvis du er på "Banana Pancake Trail" og krydser grænsen til Cambodja eller Laos, stopper din forbindelse. For en problemfri rejse i flere lande anbefaler vi stærkt vores Asia Regional eSIM, som dækker Vietnam, Cambodja, Thailand og Laos med én enkelt plan. 

Ja, men det varierer. Du vil have fremragende 4G/LTE-dækning i alle byer (Hanoi, Ho Chi Minh, Da Nang) og byer. På Ha Long Bay krydstogter er signalet stærkt, når det er tæt på kysten, men det kan være intermitterende eller langsomt, når man sejler dybt ind i kalkstenskarsterne. For bjergrige områder som Sapa og Ha Giang-løkken vil du have et godt signal i byerne, men du bør forvente døde zoner, mens du kører på fjerntliggende bjergpas. 

 For at give dig den bedste dækning i dette lange, tynde land, forbinder vores eSIM til top-tier udbydere, typisk Viettel eller Vinaphone. Viettel anses for at være det bedste netværk (som militærets netværk) med den mest omfattende dækning, især i landdistrikter og bjergområder, hvilket sikrer, at du forbliver forbundet, hvor andre netværk svigter. 

Ja, absolut. Grab er den essentielle "super-app" i Vietnam til booking af ride-hailing (biler og motorcykler) og levering af mad. Vores eSIM giver hurtige data med lav forsinkelse, hvilket er afgørende for at bestille en Grab fra lufthavnen (Hanoi - NOI eller Ho Chi Minh - SGN), spore din chauffør i realtid og bruge Google Maps til at navigere i de kaotiske gader. 

 Det gør de fleste moderne telefoner, men du skal tjekke vores specifikke liste her: eSIM-kompatible enheder for at være 100 % sikker, før du køber. 

Du vil have 4G-signal for det meste af kystrejsen mellem Hanoi og Ho Chi Minh City, men forvent, at forbindelsen falder i tunneler eller fjerntliggende sektioner nær Hai Van-passet. 

Ja. Dækningen er stærk i Can Tho og på vandet på Cai Rang Floating Market, så du kan dele billeder af bådleverandørerne med det samme. 

Du vil generelt have signal ved besøgscentrene og indgangene til Paradise Cave eller Phong Nha Cave, men dækningen er naturligvis tabt, når du går dybt under jorden. 

Ja. Dækningen er fremragende i den fodgængervenlige Hoi An Ancient Town, som er afgørende for at bruge oversættelsesapps med lokale skræddere eller finde de bedste banh mi-steder.
