Huawei Mate 90 Pro Max Lets You Use Three SIMs Simultaneously

Huawei has done something no other phone maker offers: the new Mate 90 Pro Max lets you use three SIMs simultaneously. The flagship launched in China alongside the rest of the Mate 90 series, and its triple-SIM capability is confirmed on Huawei’s official specifications page. Here is how it works and what else the phone packs.

How three SIMs simultaneously works on the Mate 90 Pro Max

The Huawei Mate 90 Pro Max supports two physical SIM cards and two eSIMs in hardware, but it allows two physical SIMs and one eSIM to stay active at the same time. That means three live connections at once, something no mainstream flagship currently matches. Huawei notes one limitation: two of the three active connections must be from the same Chinese carrier.

Most flagship phones today support dual SIM standby, which keeps two lines reachable at once. Keeping three SIMs simultaneously active is a much bigger engineering step, because the modem, antennas, and power management all have to juggle an extra live connection. That is why no other mainstream flagship currently matches what the Mate 90 Pro Max can do.

According to Huawei’s specifications page, the phone can hold two nano SIM cards in its tray plus two eSIM profiles stored digitally. In practice, three SIMs simultaneously means the two physical SIMs and one eSIM stay live together, and you can switch which eSIM profile is active without touching the tray.

There is one important catch. Huawei says two of the three live connections must come from the same Chinese carrier, so using three SIMs simultaneously is currently tied to domestic network rules in China.

Huawei Mate 90 Pro Max specs

Beyond the SIM trick, the Mate 90 Pro Max is a full flagship. The same engineering that lets it keep three SIMs simultaneously active is paired with the Kirin 9050 Pro chipset, a 6.9-inch display, a triple rear camera setup, and a 6,800mAh battery. It launched in China alongside the Mate 90, Mate 90 Pro, and Mate 90 RS.

The Kirin 9050 Pro continues Huawei’s push to power its flagship phones with in-house silicon. Combined with a large 6.9-inch display, the phone is aimed squarely at buyers who want a big screen for video, work, and gaming.

Camera hardware follows the Mate series tradition of a triple rear camera system with heavy computational photography, while the 6,800mAh battery is one of the largest ever fitted to a mainstream flagship.

The rest of the lineup covers different needs and budgets: the standard Mate 90, the Mate 90 Pro, and the Mate 90 RS, which usually adds premium materials and higher storage tiers.

Why three SIMs matter

Dual SIM has been standard for years, especially in Asia, Africa, and the Middle East, where people juggle work and personal lines or mix carriers for better coverage and roaming rates. Using three SIMs simultaneously takes that flexibility further: two numbers plus a travel eSIM, or separate work, personal, and data lines, all live without swapping anything.

Frequent travelers stand to gain the most. A local data eSIM can sit alongside a home number and a work line, so calls and messages keep arriving on all three without the usual airport routine of swapping cards.

Business users get a cleaner split too. With work, personal, and a dedicated data line all live at once, there is no need to carry a second phone or rely on call forwarding.

Coverage is another angle. In areas where no single carrier covers every route, keeping two carriers active plus a data eSIM means the phone can fall back to whichever network is strongest at the moment. That is the real promise of three SIMs simultaneously: redundancy and flexibility without carrying two phones.

Availability

For now, the Mate 90 Pro Max is a China launch, and the three-SIM feature is tied to Chinese carrier requirements. Huawei has not announced international availability or pricing.

That leaves international buyers waiting. Huawei’s recent flagships have seen limited releases outside China, and the company has said nothing about whether the Mate 90 Pro Max will travel further.

Even if it does go global, using three SIMs simultaneously depends on carrier support, so buyers abroad would need Huawei and their local networks to confirm how it behaves before counting on it. We will keep tracking this story; for more smartphone news, visit Axeetech.
