Billion Connect review: our honest take

Billion Connect is the travel eSIM brand of Hong Kong-based WeiTaiGe Technology, sold through its BC eSIM companion app as well as its website, with plans delivered as an emailed QR code that starts once the eSIM connects to a network at the destination. Its fixed-data plans are listed with an unlimited 128kbps fallback after the high-speed allowance runs out, so you are throttled rather than cut off mid-trip. On eSIMAdvice it currently lists 482 live plans across 88 countries, starting at $1.32, including a range of unlimited-data options.

Match the plan to your trip length and expected data usage before choosing Billion Connect.

Check whether hotspot, 5G, roaming partners, and fair-use limits fit your phone and destination.

Confirm final taxes, activation timing, refund terms, and supported networks on the provider checkout page.

👍 What we like

✓Fixed-data plans are listed with an unlimited throttled-speed fallback at 128kbps after the high-speed allowance, so you keep basic connectivity instead of losing service

✓Unlimited-data plans are available for many single countries and Asian regional bundles, including short daily-unlimited options

✓Dedicated BC eSIM app handles purchase, QR installation and data tracking, with English, Japanese, Spanish and Traditional Chinese language support

✓Validity starts when the eSIM connects at the destination, so you can install the QR code at home and keep the line disabled until you land

✓Very low entry price: live plans on our site start at $1.32, with tiny allowances suited to short trips

✓Apple Pay and Google Pay accepted alongside Visa and Mastercard

👎 Worth noting

–Top-ups are not advertised for existing plans, so running out of high-speed data usually means buying and installing a new plan

–No published refund window; refunds vary by plan type and are decided case by case through support

–The plans we list are data-only with no phone number or SMS, so calls and texts depend on WhatsApp or similar apps

–No no-expiry or pay-as-you-go options: plans run on fixed validity periods

About Billion Connect

You buy either on the Billion Connect website or in the BC eSIM app (iOS and Android), paying with Visa, Mastercard, Apple Pay or Google Pay. After checkout you receive an email with a QR code and installation instructions; Billion Connect recommends installing and enabling the eSIM at your destination, or, if you install it before departure, leaving the line disabled until you arrive, because the plan starts once the eSIM connects to a network at the destination. The app then tracks remaining data for each plan. The plans we list are data-only (no phone number or SMS), and top-ups for an existing plan are not advertised, so if you run out of high-speed data the usual fix is buying a new plan rather than recharging the old one.

Billion Connect — quick answers

What is the cheapest Billion Connect eSIM plan?

The cheapest live Billion Connect plan on eSIMAdvice is $1.32. Across the catalog we track 482 live plans in 88 countries, including unlimited-data options for many destinations, so short-trip travelers with light data needs are particularly well served.

How is Billion Connect priced compared to its plan sizes?

Billion Connect leans on small, short-validity plans, which keeps its entry prices low: live plans on our site start at $1.32. Unlimited plans exist for many single countries and Asian regional bundles, but there is no unlimited global plan, and since top-ups for an existing plan are not advertised you should size your data allowance for the whole trip up front.

When does a Billion Connect eSIM start its validity period?

The plan starts once the eSIM connects to a network in the destination. Billion Connect recommends installing the QR code at the destination, or installing it before departure and leaving the line disabled until you arrive, so the validity clock does not start early. All plans run on fixed validity periods rather than open-ended credit.

What happens when I use up my high-speed data on Billion Connect?

Billion Connect's fixed-data plans are listed with an unlimited fallback at 128kbps once the high-speed allowance is exhausted, so you keep a slow connection for messaging and maps instead of being cut off. Top-ups for an existing plan are not advertised, so restoring full speed generally means buying a new plan.

Do I need the BC eSIM app to use Billion Connect?

No, but it helps. The BC eSIM app, published by WeiTaiGe Technology, lets you buy plans, install the eSIM via QR code and monitor remaining data, and it is where the 24/7 support chat lives. If you buy on the website instead, the QR code and setup instructions arrive by email, so the app is optional for installation.
