Vietnam MobiFone eSIM FAQs

Plan and setup answers for your ByteSIM eSIM.

Which Vietnam eSIM plan should I choose?

For the ByteSIM Vietnam MobiFone eSIM, choose a plan that covers your full trip and matches your daily data needs.

Local calls: 5GB/Day · 15 Days and 6GB/Day · 30 Days each include 100 local minutes. The 5GB/Day · 15 Days plan also includes 50 outgoing SMS.

International calls: 4GB/Day · 20 Days includes 20 minutes to 14 destinations. Compare all eight MobiFone plans.

Will this eSIM work on my phone?

Your phone needs eSIM support and must be carrier-unlocked. Check the exact model and regional version on our compatible device list.

Do I need to submit my passport?

No passport upload or separate registration is required for the ByteSIM Vietnam MobiFone eSIM.

Can I install the eSIM before I travel?

Yes. Install on Wi-Fi before departure using one-tap installation in the ByteSIM App or your emailed QR code. Switch the eSIM on when you arrive in Vietnam.

When does my plan start, and how are days counted?

The ByteSIM Vietnam MobiFone plan starts on its first connection to MobiFone in Vietnam. Each plan day is a continuous 24-hour period.

For example, a 7-day plan starting at 14:00 on October 1 expires at 14:00 on October 8, Vietnam time. Installing the eSIM before your trip does not start this countdown.

When does daily data reset, and what if I use it up?

ByteSIM Vietnam MobiFone plans have a daily data limit. Mobile data stops when you use it up.

Your daily allowance resets at 00:00 Vietnam time (UTC+7) while the plan is valid. This local midnight reset is separate from the continuous 24-hour periods used to calculate plan expiry.

Do I need to turn on data roaming?

No. ByteSIM's Vietnam MobiFone eSIM is a local eSIM and does not require data roaming. Turn on the eSIM and select it as your mobile data line.

Does every plan include a Vietnam number?

All eight ByteSIM Vietnam MobiFone plans include a +84 Vietnam number with free incoming calls and incoming SMS in Vietnam. Outgoing calls and outgoing SMS are included only on selected plans; see the plan comparison for details.

How do I check my number and remaining data?

Once connected in Vietnam, use your MobiFone line for these checks.

Remaining data: dial *090*5# or text KT ALL to 9199.

Your number: dial *0#.

Can I receive OTP codes from Grab, Zalo or banks?

The +84 number on this ByteSIM MobiFone eSIM can receive SMS, but verification codes (OTP) are not guaranteed. Grab, Zalo, banks and other services apply their own verification rules.

Can I top up, extend my plan or keep the number?

ByteSIM Vietnam MobiFone plans cannot be topped up or extended, and the included number cannot be retained after the plan expires. Choose a plan that covers your full trip.

Can I share my connection through a hotspot?

Yes, hotspot sharing is supported. Enable your phone's Personal Hotspot or Wi-Fi hotspot to connect a laptop, tablet or another phone.

Which network does this eSIM use, and is 5G available?

This local Vietnam eSIM is provided by ByteSIM and connects to MobiFone's 5G/4G LTE network. 5G requires a compatible phone, 5G enabled in settings and MobiFone 5G coverage. Where 5G is unavailable, your phone can use 4G LTE if covered. Signal can be weaker in remote mountain areas.

Check your route on the nPerf MobiFone map. It shows user measurements, not guaranteed coverage at every location.

What should I do if I cannot connect?

Check that the ByteSIM eSIM is on and selected for mobile data. Toggle airplane mode, then restart your phone if needed.

Still offline? Connect to Wi-Fi and contact ByteSIM support on WhatsApp or email. Keep the eSIM installed while we troubleshoot.
