What is an eSIM and How Does it Work? Complete Beginner's Guide
Planning a trip to Puerto Rico or the Caribbean? You've probably come across the term eSIM and wondered exactly what it is and how it works. In this guide, we'll walk you through everything you need to know about this technology that's transforming the way travelers stay connected abroad.
What is an eSIM?
An eSIM (embedded SIM) is a digital SIM card built directly into your phone or device. Unlike a traditional physical SIM — that small plastic card you insert into your phone — an eSIM has no physical form: it's soldered onto your device's motherboard and can be programmed remotely.
The key difference is simple: you don't need to insert or remove anything. Everything happens through software, instantly and without visiting any store.
When did eSIM technology emerge?
eSIM technology began expanding in the consumer market around 2018 with the iPhone XS. Today in 2026, virtually all mid-range and high-end phones support it, including iPhone 11 and later, Samsung Galaxy S20+, Google Pixel 3 and newer models.
How does an eSIM work? Step by step
Activating a Bingo eSIM is surprisingly simple:
- Purchase your plan at bingowireless.net/en/store/puerto-rico — choose the GB and duration you need
- Receive a QR code by email within 2 minutes of purchase
- Scan the QR code from your phone: go to Settings → Mobile Data → Add eSIM
- Your phone downloads the carrier profile directly from the internet
- Done — you have active data in Puerto Rico without needing a physical card
No stores, no lines, no waiting. You can buy the eSIM at the airport while waiting for your flight and arrive in Puerto Rico already connected.
eSIM vs Physical SIM: the key differences
| | eSIM | Physical SIM | |---|---|---| | Activation | Instant (2 minutes) | 30-60 minutes at a store | | International travel | Activate before you leave | Find a store upon arrival | | Multiple plans | You can have several | One at a time | | Risk of loss | None (built into phone) | High (small card) | | Compatibility | Modern phones | All phones |
Advantages of eSIM for traveling to Puerto Rico
1. No roaming, no surprise bills
Every traveler's biggest fear is opening their phone bill after a trip and finding $200+ in roaming charges. With a Bingo eSIM, you pay a flat rate starting at $5.99 USD — no surprises.
2. Keep your home number active
One of the biggest advantages of eSIM is that you can use it alongside your main SIM. Your home number stays active for calls and SMS, while the Bingo eSIM handles all your data in Puerto Rico. Two lines on a single phone.
3. Multi-carrier coverage in Puerto Rico
Bingo eSIMs have access to T-Mobile, Liberty, and Claro networks in Puerto Rico. That means if signal is weak from one carrier in a given area, your phone automatically connects to the strongest one. It's the best possible coverage on the island.
4. Hotspot included at no extra cost
With Bingo you can share your connection as a WiFi hotspot with other devices — laptops, tablets, other phones — at no additional charge. Perfect for families or travel groups.
Is my phone compatible with eSIM?
Most modern phones are compatible. Here are the most common ones:
iPhone: From iPhone XR/XS (2018) onward. iPhone 14 and later are eSIM-only in the US.
Samsung: Galaxy S20 and newer, Galaxy Z Fold/Flip, Galaxy A54 and higher.
Google Pixel: Pixel 3 and newer.
Others: OnePlus 12, Motorola Razr, Huawei P40 Pro (with limitations).
Important: Your phone must be unlocked to use a Bingo eSIM. If you bought it directly from Apple, Google, or on Amazon as "unlocked," you're good to go. If you bought it with a carrier contract, check with your provider if it's already unlocked.
You can verify your device's compatibility on our compatibility page before purchasing.
Is eSIM secure?
Absolutely. eSIM technology uses the same security standards as physical SIM cards, defined by the GSMA (international association of mobile operators). Your profile is encrypted and can only be downloaded once — no one can "steal" your eSIM the way they could steal a physical card.
Plus, if you lose your phone, the eSIM is tied to your device — it can't be removed and used on another phone without your authorization.
