MobiFone and travel eSIM in Vietnam
MobiFone is one of the networks your eSIM may use in Vietnam. Here is who actually decides which network you get, and what to do with that.

Quick answer
- 100 of the 100 Vietnam plans we sell name MobiFone as a reachable network, at 4G and 5G.
- MobiFone runs LTE on B3, B8; your phone needs at least one of them.
- Travel plans connect by roaming, so no plan can promise one specific network.
MobiFone in brief
Vietnam's 2G networks were scheduled to be fully shut down by 15 September 2026; VinaPhone and MobiFone are to keep 3G running alongside 4G and 5G.
We are not a reseller for this operator and we have not run our own field speed tests. The band and network details below come from the sources listed at the end of the page.
MobiFone's bands and technology
| Item | MobiFone |
|---|---|
| LTE (4G) | B3, B8 |
| 5G NR | Not verified |
| 5G launched | Not verified |
| 3G | Still running |
| Network code (MCC-MNC) | 452-01 |
Checked against the sources on 2026-10-12. Only the bands a source confirmed are listed; the network may run others too.
An eSIM can only use MobiFone if your phone supports at least one band in this table. Before you fly, open your model's spec page on the maker's site and compare its LTE and 5G band lists.
The plans on our shelf that name MobiFone
From the supplier record behind each package, 100 of the 100 plans we currently sell for Vietnam declare MobiFone as a network the profile can reach, at 4G and 5G. The figure comes from the same catalogue that prices the plan pages, and it moves when the supplier revises the record.
A plan naming MobiFone means the network sits in the list the profile may choose from. It does not mean your handset will stay on it. The priority order is the supplier's, and the signal where you stand decides.
MobiFone beside the other networks in Vietnam
| Network | LTE bands | 5G bands |
|---|---|---|
| MobiFone | B3, B8 | Not verified |
| Viettel | B8, B3 | n28, n41 |
A band shared across networks is one a single phone can use on all of them.
Why plans do not name a fixed network
Nearly every travel eSIM is a roaming product: the profile picks a network by an order the supplier sets, not by the buyer. If MobiFone is weak where you are, try selecting Viettel or Vinaphone manually in the network settings, and keep data roaming on for the eSIM profile.
FAQ
Will my eSIM definitely connect to MobiFone?+
100 of our plans name MobiFone as reachable, but that is not a guarantee. Travel plans run over roaming agreements, so the network depends on the supplier behind the plan, your device and where you are.
Which bands does my phone need for MobiFone?+
At least one of these, LTE: B3, B8. Your phone's band list is on the maker's spec page for your model, under "Cellular" or "Network".
Does MobiFone run 5G, and will my plan get it?+
We could not confirm MobiFone's 5G status from an official source. Our plans that reach this network list 4G and 5G.
How do I see which network I am on?+
Check the carrier name at the top of the screen, or open the mobile-network settings and look at the operator list. If signal is poor, try selecting a network manually instead of automatic, but only one your plan actually supports.
