Planning a trip and need data fast? If you pay with USDT (TRC20/ERC20), you skip KYC and get instant activation. We compare two top 7-day eSIMs: Japan (from NipponSIM) and Vietnam (from VietData). Both cost around 10-15 USDT, but which fits your needs?

Japan eSIM 7 Day Overview

NipponSIM's Japan 7-day plan offers 5GB data at 12 USDT (TRC20). Covers major cities like Tokyo, Osaka, and Kyoto. Speeds up to 50 Mbps (4G LTE). No activation fee. Supports eSIM on iPhone XS and later, and most Android models. Valid until December 2026.

Vietnam eSIM 7 Day Overview

VietData's Vietnam 7-day plan gives 6GB data for 10 USDT (ERC20). Works nationwide, including Hanoi and Ho Chi Minh City. Speeds up to 40 Mbps (4G). eSIM compatible with most modern phones. Also valid until end of 2026.

Price Comparison

Japan: 12 USDT for 5GB (2.4 USDT/GB). Vietnam: 10 USDT for 6GB (1.67 USDT/GB). Vietnam is cheaper per GB. But Japan's network is often faster and more reliable.

Coverage & Speed

Japan's 5GB plan uses Docomo and SoftBank networks—excellent in cities and rural areas. Vietnam's 6GB relies on Viettel, strong in urban centers but spotty in remote regions. For heavy streaming, Japan wins; for browsing, Vietnam is fine.

USDT Payment Advantages

Both accept USDT via TRC20 or ERC20. No bank details needed. Instant activation—buy, scan QR, install eSIM. Great for privacy-focused travelers. No hidden fees.

Which Should You Choose?

Pick Japan eSIM if you prioritize speed and coverage, especially for cities. Go with Vietnam eSIM if you want more data per USDT and are visiting main hubs. Both are solid for 7-day trips.
