Return and Exchange Policy
Faulty on arrival: if a device arrives defective — a broken screen, a connectivity fault — we replace it with a new one straight away. No forms, no waiting on the manufacturer.
Warranty: hardware wallets carry a 1-year warranty, and claims are handled by us rather than an overseas support queue. CryptoSafe steel backup products are sold without warranty, as stated on those product pages.
Change of mind or wrong model: we do not accept returns or give refunds, whether or not the box has been opened. We accept returns for defective products only, which we exchange within 30 days of delivery. This is a security limitation of these devices: once a device has left us, we cannot assure the next customer that it has not been interfered with.
How to arrange an exchange for a faulty item
- Message us on LINE at @siambc or email order@siambc.com before sending anything back.
- Include your order number, what is wrong, and a photo or short video.
- Send the item back to us at your own shipping cost. Once we have checked it, we exchange it.
Refunds: faulty items are exchanged rather than refunded.
Pairs well with
The Trezor Safe 3 is the most affordable Trezor with a certified secure element. It is the model to choose if you want a security chip without paying flagship prices.
Certified secure element
- OPTIGA Trust M (V3) secure element, certified to Common Criteria EAL6+
- Trezor describes it as NDA-free, meaning its behaviour can be independently examined rather than hidden behind a vendor agreement
- Tamper-evident casing with anodized aluminum backplates, so interference is visible
Specifications
- 0.96-inch monochrome OLED display, 128 x 64 px
- USB-C connection. No Bluetooth, no NFC, no microSD.
- 59 x 32 x 7.4 mm, 14 g
- Durable PMMA plastic with a hidden-tilt effect and anodized aluminum backplates
- 180 MHz ARM Cortex-M4 processor
- CE and RoHS certified
Security and backup
- Open-source security and design
- 12, 20 and 24-word wallet backup
- Advanced Multi-share Backup — split your backup across multiple shares
- PIN and passphrase protection, entered on the device
- Two-button confirmation for every transaction
Bitcoin-only option
Trezor also sells a Bitcoin-only edition of the Safe 3, running firmware built exclusively for Bitcoin with no altcoin code. Less code means less to go wrong. Ask us if you would prefer that version.
Coins and compatibility
- Thousands of coins and tokens supported
- Android, Windows, macOS and Linux compatible via Trezor Suite
- Limited on iPhone — Trezor's wording is "No swap, send, setup or device management on iOS". Full iOS functionality requires the Safe 7.
Common questions
How is it different from the Trezor Model One?
The Safe 3 adds a certified EAL6+ secure element, USB-C, tamper-evident casing and Multi-share Backup. The Model One has none of those.
How is it different from the Safe 5?
The Safe 5 adds a color touchscreen, Gorilla Glass, haptic feedback and a microSD slot. Both use the same EAL6+ secure element.
Can I use it with an iPhone?
Only in a limited way. Checking balances, buying and receiving work; sending, swapping and setup do not. The Safe 7 is the model with full iOS support.
What is Multi-share Backup?
It splits your recovery backup into several shares, so a single lost or stolen share does not expose your wallet.
Buying from SIAMBC
SIAMBC is Thailand's authorized Trezor distributor, with a physical store in Bangkok. Every unit is new, sealed and sourced directly. Support is available in Thai and English.
ONE RULE TO REMEMBER
Anyone who asks for your recovery phrase is a scammer. No exceptions.
Neither SIAMBC nor Trezor will ever ask for it, whatever reason is given — warranty claims, identity verification, system updates or account recovery. Those words are the key to your funds. Whoever has them owns your crypto, and it can never be recovered.

How to check your device is genuine
- The box must be shrink-wrappedThe Safe 3 box comes wrapped in clear or watermarked plastic. If the wrap is torn or looks as if it was opened and rewrapped, do not use the device and contact us right away.
- The holographic seal over USB-C must be intactThere are two seal designs: the original one and an updated one from April 2024 with the UK CA mark. Both are genuine. What matters is that the seal is intact and untorn. If it is damaged or missing, stop the setup and contact us.
- The device must show no signs of tamperingLook around the body, the edges and the seams. There should be no pry marks, scratches, glue residue, or loose or badly fitted parts. If you find any of these, do not use the device and contact us right away.
- The cards come in two versions, both genuine2023 units come with 12-word cards labelled Recovery seed; 2024 units come with 20-word cards labelled Wallet backup. The cards must be completely blank. If any words are already written on them, never use the device.
- A new device ships without firmwareEvery Safe 3 leaves the factory without firmware, and Trezor Suite installs correctly signed firmware during setup. If the device already has firmware, do not use it and contact us right away.
- Let Trezor Suite check the deviceOn first connection, Trezor Suite uses the secure element to confirm the device is genuine, and it verifies the firmware signature every time you connect. Do not turn off Device Check in settings, and only download Trezor Suite from trezor.io/start.
Trezor Safe 3 FAQ
How much is the Trezor Safe 3?
3,790 ฿ at SIAMBC, an official Trezor reseller in Thailand. Free shipping nationwide, delivered in 1 to 2 days.
Does it work with iPhone?
Only partly. On iPhone you can view balances and receive, but setup and sending need a computer or an Android phone over USB-C. If you mainly use an iPhone, the Trezor Safe 7 works fully with iPhone over Bluetooth.
Does it need charging?
No. The Safe 3 has no battery and switches on when you plug in the USB-C cable, so there is no battery to wear out.
How is the Trezor Safe 3 different from the Safe 5?
They use the same secure element (OPTIGA Trust M), so security is the same level. The Safe 5 has a larger color touchscreen and a glass front, while the Safe 3 uses 2 buttons, is smaller and lighter, and costs less.
How many words is the Seed Phrase?
Units made from June 2024 use 20 words by default; earlier units use 12 words. Either way you can choose 12, 20 or 24 words, and recover 12-, 18- or 24-word wallets.
If you have any questions, you are always welcome to contact us. We'll get back to you as soon as possible, within 24 hours on weekdays.

Before you buy
Are your products genuine?
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.
How long does delivery take?
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.
Can I collect from your store instead?
Yes. We are in Thawi Watthana, Bangkok, open Monday to Saturday, 9:00 AM to 5:00 PM. You are welcome to come in, see the devices in person and ask questions before you buy. We answer in Thai and English. Find us here.
What warranty do I get?
Hardware wallets carry a 1-year warranty, claimed directly through us, with no waiting in an overseas support queue.
If a device is faulty out of the box, we replace it with a new one straight away. No forms, no waiting on the manufacturer.
The exception is the CryptoSafe range of steel recovery phrase backups: these products carry no warranty and cannot be returned or exchanged, as stated on their product pages.
How can I pay?
Credit card, bank transfer, or cash on delivery. You can also pay in person at our Bangkok store.
Can I set it up myself?
Yes, and you should do every step yourself. It takes a few minutes: you press every button on the device, create the wallet and write down your recovery phrase on your own.
Our step-by-step guides walk you through each step. If you get stuck, our team can answer on LINE or by phone, without ever seeing or asking for your recovery phrase.
Which model should I choose?
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.
What happens if I lose my hardware wallet?
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.
Will anyone ever ask for my recovery phrase?
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.
