Blockstream Jade Core

Yes. Every device we sell is new, sealed, genuine stock from authorized channels. SIAMBC has been Thailand's hardware wallet specialist since 2016 and has a physical store in Bangkok you can walk into.

This matters more than it sounds. A hardware wallet bought from an unknown marketplace seller can arrive already set up by someone else, with a recovery phrase they know. It is the one purchase where the seller genuinely matters.

Orders normally arrive within 1 to 2 business days, depending on where you are — faster if you are in Bangkok.

Need it today? We can send it by Grab or LINEMAN for same-day delivery. Call us or message us on LINE to arrange it, pay by bank transfer, and it goes out immediately.

You are also welcome to collect from our Bangkok store.

可以，而且每一步都应该自己来，几分钟就能完成。设备上的每个按键都由你自己按，钱包由你自己创建，助记词也由你自己抄写。

我们的分步使用指南会带你走完每一步。遇到问题，我们的团队可以通过 LINE 或电话解答，全程不会看到，也绝不会索要你的助记词。

It depends on the phone you use and what you are protecting. The most common mistake is buying a wallet that does not work with your phone — the Ledger Nano S Plus does not support iPhone at all, and most Trezor models are view-only on iOS.

Compare every model side by side, or ask us. We will tell you honestly which one fits.

Nothing, as long as you still have your recovery phrase. The device only holds the keys — buy any compatible wallet, enter your phrase, and your crypto is back.

The real risk is losing the phrase itself. That is why we suggest keeping it on steel rather than the paper card in the box. Paper burns, water ruins it, and in Thailand termites eat it.

No. Anyone who asks for it is a scammer, without exception. Neither SIAMBC nor any manufacturer will ever ask for your recovery phrase — not for a warranty claim, not for identity verification, not for a firmware update. Whoever has those words owns your crypto, and it can never be recovered.
