My phone has two SIM slots - does that mean it supports eSIM?

Not necessarily. Having two SIM slots means your phone supports Dual SIM - but that's a physical feature, not an eSIM feature. The two are completely separate technologies, and one does not imply the other.

What's the difference?

A physical SIM slot is designed to hold a small removable chip - the SIM card you get from your carrier. Dual SIM simply means your phone has two of these slots, allowing you to use two phone numbers or two carriers at the same time. This has been around for decades and is common in many mid-range and budget Android phones.

An eSIM, on the other hand, is a chip that's permanently built into your phone's hardware. It can't be removed or swapped. Instead of inserting a physical card, you download your carrier plan digitally - which is exactly how Gohub works. For your phone to support this, the eSIM chip needs to have been included by the manufacturer when the phone was made.

So what does this mean in practice?

A phone can fall into any of these three categories:

• Two physical SIM slots, no eSIM - very common in older Android phones and devices made for certain markets. Dual SIM, but not eSIM-compatible.
• One physical SIM slot + one eSIM - common in modern iPhones and flagship Android phones. This is the setup that works with Gohub.
• eSIM only, no physical SIM slot - found in some newer iPhone models (iPhone 14 and later in the US). These work with Gohub as well.

→ The safest assumption is: don't rely on the number of SIM slots to judge eSIM support. The only way to know for sure is to check your settings directly.
