UK eSIM Connectivity — Networks, Coverage & Plan Details

AloOui offers UK travel eSIMs with fixed-data plans from 1GB to 100GB, daily-unlimited Lite, Essential and Plus options, and separate variants with recorded calls and SMS allowances. O2 UK, Three UK and Vodafone UK appear in the listed network groups; each group applies only to the variants referencing it. Data-only plans do not inherit calls or SMS from combined-service plans. The Unlimited 30 Days V2 variant has a conflicting service classification, so no calls or SMS allowance is inferred for it.

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.
Provider-listed: operator and network listings, general guidance and country-level references, 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 UK 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: 36 exact variant records from United Kingdom eSIM. Regional, Flash Sale and separate number-service products are excluded from these country-product records.

Exact variant records

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. The V2 row has a Conflicting service classification and does not inherit another variant's voice or SMS allowance.

Unlimited does not mean unlimited full-speed data. Total fixed-data allowances are not daily refills. Daily Lite, Essential and Plus conditions are not borrowed for combined-service variants. Premium and Platinum remain separate plan families; neither is inferred from Plus or another tier.

Network records by exact variant group

Operator identities and identifiers are Provider-listed, as recorded in the AloOui catalog. Populated exact-variant technology fields are AloOui catalog data (Store-documented). Technology listings do not guarantee 5G, performance or access at a particular location.

Network group N1

Network group N2

O2 UK's exact-variant technology field is empty for this group. The separately identified Provider-listed country reference held by AloOui below retains useful network information without claiming exact-plan technology confirmation.

Installation and service conditions by exact variant group

These tables show recorded conditions and allowances only. Details not recorded for an exact variant are omitted rather than inferred; general setup guidance is provided separately below. Calls and SMS allowances apply only to the corresponding combined-service variants.

Condition group C2

Condition group C3

Condition group C4

Condition group C5

Condition group C6

Condition group C7

Conflicting service records

Conflicting: United Kingdom Unlimited 30 Days V2 is classified as Data, calls & SMS, while its own service field says Data only. No voice or SMS allowance is established for this exact variant, and none is borrowed from another plan.

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. This guidance is separate from exact-variant APN records and does not establish a separate sharing cap.

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. This guidance is not applied to fixed-data, Premium or combined-service variants without corresponding evidence.

AloOui's travel-eSIM activation guidance starts validity on connection to a supported network at the destination, not installation alone. This is AloOui's general activation guidance, separate from the exact-variant record fields, and does not establish activation conditions for separate number services.
