FAQ

Common Questions
About B2B eSIM

Everything you need to know about the Linkbear eSIM platform and how it works.

Does my phone support eSIM?

Currently, mainstream eSIM-enabled devices include: iPhone: iPhone XS / XR and later (note: China-mainland models do not support eSIM); Android: Google Pixel 3 and later; Samsung Galaxy S20 and later, Fold series; select Huawei international models; Tablets / Laptops: iPad Pro (3rd gen+), Surface Pro, and some other models. Dial *#06# — if an EID number appears, your device supports eSIM.

How do I activate an eSIM?

Three common methods: QR Code Scan: scan the QR code provided by your carrier to auto-download the profile; Manual Entry: go to Settings → Add Cellular Plan, then manually enter the SM-DP+ address and activation code; Carrier App: download the profile directly through your carrier's app.

How many eSIM profiles can one device store?

It depends on the device model: iPhone: up to 5-10 profiles stored, but only 2 can be active simultaneously (or 1 eSIM + 1 physical SIM); Pixel: typically supports 5+ stored profiles, with 1-2 active at a time; varies across devices — check the manufacturer's specs for details.

Can I use eSIM and a physical SIM at the same time?

Most modern devices support Dual SIM Dual Standby (DSDS), allowing you to activate 1 eSIM + 1 physical SIM, or 2 eSIMs simultaneously. However, only one line can use 5G data at a time.

How deep does white-label customization go?

Very deep. Custom domain, brand logo & color scheme, autonomous pricing, admin dashboard, multi-language, multi-currency, and payment gateway configuration. End users experience your brand end-to-end — Linkbear is completely invisible. We provide infrastructure; you own the customer relationship.

How long does API integration take?

Standard API integration can be completed in 1-2 business days for Sandbox testing. White-label platform setup typically takes 3-5 business days. We provide comprehensive API documentation, SDKs (Python / Node.js / Go), and dedicated technical support to ensure fast onboarding.

Will customers mind that it's data-only without voice?

Global trends show data demand far exceeds voice for travelers. Most use WhatsApp, WeChat, Zoom, or FaceTime — all data-based. Data-only means simpler compliance, lower costs, and more competitive pricing — exactly what B2B partners and their customers want.

How do you ensure network stability and speed?

We connect to multiple carrier networks in each country with automatic best-signal switching. Edge nodes globally ensure low API latency. 99.9% SLA commitment, real-time network monitoring, and 24/7 on-call operations keep your business always online.

Is there a minimum order quantity?

No minimum for our Starter plan — perfect for validation. Growth plans benefit from 500+ monthly volume for best wholesale pricing. Enterprise plans are fully custom. Our pricing is tiered — the more you sell, the better your unit cost — but there's no forced minimum.
