China Physical Unicom SIM Card 5G 90 Days 90GB Data - Reliable Travel

In this review the China Physical Unicom SIM Card is examined for travelers and short-term visitors who need straightforward mobile data and voice service inside Mainland China. The single biggest reason to buy is the balance of a large 90GB data allowance with a substantial 600 minutes and 600 texts for domestic use, all on a physical China Unicom 5G SIM that works right away after landing in many cities. The card is designed for Mainland China use only and includes a Chinese phone number, making it a practical choice for people who want immediate local connectivity without complex setup.

Key Features

• 90GB Data: A generous data allowance that covers heavy browsing, maps, and streaming during a typical 90 day stay without frequent top-ups.
• 600 Minutes Domestic Talk: Enough included talk time for local calls to taxis, hotels, and business contacts without relying on internet calling alone.
• 600 Domestic Texts: Useful for services and verification codes that still rely on SMS within China.
• China Unicom 5G Network: Access to local 5G and 4G bands for fast internet and good signal quality in urban areas that support band 78 and band 3.
• Physical SIM with 3-in-1 Adapter: Standard nano, micro, and full-size configuration makes it easy to fit most phones without extra tools.
• Activation Process: Activation is handled after delivery by emailing required information and a passport copy for government registration, which is deleted after use.

Who It's For

This SIM is best for international travelers, business visitors, and short-term residents who will spend most of their time in Mainland China and need local data plus conventional voice and SMS service. It is particularly well suited to users who prefer a physical SIM rather than an eSIM and who want a Chinese phone number for local services.

It is not appropriate for those who plan to use the SIM outside Mainland China, since coverage is for China only. Buyers of Google Pixel series phones should check compatibility, as some Pixel models have software issues that can affect voice calling; if voice functionality on a Pixel is essential, consider using a different handset.
