Vietnam eSIM Connectivity — Networks, Coverage & Plan Details

AloOui offers data-only Vietnam travel eSIMs with fixed-data plans from 1GB to 100GB and daily-unlimited Lite, Essential and Plus options. Viettel is the listed operator; network access and performance depend on the offer, device and location. Daily-unlimited plans have daily high-speed allowances before reduced speeds apply, while fixed-data allowances are total data for the plan. AloOui states that no ID is required and no phone number, calls or SMS are included; 5G is available where supported by the network, not guaranteed everywhere.

Evidence status

Mapped — AloOui has matched the applicable variant to its fulfillment bundle. Mapping is separate from provider confirmation, field testing and network-performance confirmation.
AloOui catalog data (Store-documented): allowances and conditions recorded for the relevant variants. AloOui-stated service details are identified separately.
Provider-listed: operator and network listings and general guidance, distinguished from exact-plan confirmation.
Provider-confirmed: No offer-specific provider confirmation is recorded on this page.
Field-tested: AloOui reports real-world field testing. Specific Vietnam findings tied to a plan, device, location and time are not documented on this page; listed networks and conditions are not presented as field-test results.
Unknown: not established by the available evidence.
Conflicting: relevant sources disagree.

The absence of recorded offer-specific confirmation or detailed field-test findings does not imply that provider listings or catalog data are unreliable.

Connectivity data reviewed: October 8, 2026. The variant snapshot used here was collected on October 7, 2026. The review date is not a network field-test date.
Product scope: 29 exact variant records from Vietnam travel eSIM. Regional, Flash Sale and separate number-service products are excluded from these country-product records.

Vietnam plan and connectivity evidence

Each row uses its own AloOui catalog record. Total-plan and daily allowance bases remain distinct. Network groups N and condition groups C apply only to rows referencing them.

Unlimited does not mean unlimited full-speed data. Fixed-data allowances are total data, not daily refills. Lite records 1GB of high-speed data per day followed by up to 512 kbps; Essential records 1GB per day followed by up to 1.25 Mbps; Plus records 2GB per day followed by up to 2 Mbps. No Premium or Platinum variant is represented in these 29 records; neither is inferred from Lite, Essential or Plus.

Network records by exact variant group

Operator identity and identifiers are Provider-listed, as recorded in the AloOui catalog. The exact-variant technology field and separately held country-reference technology field are not populated and are not filled from another country or plan. AloOui's conditional 5G statement appears separately in the service conditions; it is not an offer-specific technology record or provider confirmation.

Network group N1

Installation and service conditions by exact variant group

These tables show recorded conditions and AloOui-stated service details only. Details not established for an exact variant are omitted rather than inferred; general setup guidance is provided separately below. QR installation, APN, hotspot, validity start and device requirements are AloOui catalog data (Store-documented). No-ID, data-only inclusions and conditional 5G wording are AloOui-stated, not offer-specific provider confirmation or field-test results.

Condition group C1

Published setup and daily-family guidance

Evidence: Provider-listed general guidance, separate from exact-offer provider confirmation. Published guidance supports hotspot sharing and automatic APN setup. If manual setup is needed, it specifies data.esim with username and password left blank. Vietnam's APN and hotspot availability are separately recorded as AloOui catalog data; a separate hotspot-sharing cap is not established by this general guidance.

For daily Unlimited Lite, Essential and Plus, Provider-listed guidance describes a rolling reset 24 hours after activation and every 24 hours afterwards, not a universal midnight reset. These daily-family rules are not applied to fixed-data plans.
