BuyUKeSIM takes 12 cryptocurrencies across several networks at checkout. They are not all equal: fees, confirmation speed and privacy differ a lot. Here is how to pick the right one for buying a UK +44 eSIM or travel data.
The three things that matter
- Fee - the network cost to send. On some chains this is cents; on others it can spike.
- Speed - how long until the payment confirms and your QR appears.
- Privacy - whether the payment is publicly traceable.
Fastest and cheapest: stablecoins on fast chains
USDT on TRC20 (Tron) and USDC on Polygon are usually the best all-rounders: fees of a few cents, confirmation in roughly 1-3 minutes, and stable value so the amount does not move while you pay. This is what most buyers should pick. See the TRC20 guide.
Most private: Monero
Monero (XMR) hides sender, receiver and amount by default, so the payment leaves no public trail. If privacy is your priority, this is the pick - details in Buy an eSIM with Monero.
Most familiar and liquid: BTC and ETH
Bitcoin and Ethereum are the easiest to acquire and hold, but on-chain BTC can take 10-30 minutes and ETH mainnet fees rise with network load. Great if it is what you already own; not the cheapest or fastest.
At a glance
| Option | Typical fee | Speed | Privacy | Best when |
|---|---|---|---|---|
| USDT (TRC20) | Very low | ~1-3 min | Public | Cheap and fast |
| USDC (Polygon) | Very low | ~1-3 min | Public | Cheap and fast |
| Monero (XMR) | Low | ~2-20 min | Private | Maximum privacy |
| SOL | Very low | Seconds-minutes | Public | You hold Solana |
| BTC | Variable | 10-30 min | Public | You hold Bitcoin |
| ETH | Higher at peak | ~2-5 min | Public | You hold Ether |
Which should you choose?
- Just want it done cheaply and fast: USDT (TRC20) or USDC (Polygon).
- Want maximum privacy: Monero (XMR).
- Paying from what you already hold: BTC, ETH or SOL all work.
