## eSIM for St. Lucia: common questions

### Will an eSIM work on my phone in St. Lucia?

Yes, if your phone supports eSIM and is not locked to a carrier. That includes iPhone XS and later, Google Pixel 3 and later, and most recent Samsung Galaxy models. Check the device compatibility page if you are unsure.

### When should I install the eSIM?

Install it before you travel, while you have Wi-Fi. For most plans the validity starts when the eSIM first connects to a network in St. Lucia, not when you install it. Each plan's details show how long you have to activate it.

### Can I keep my own number and WhatsApp?

Yes. The eSIM is a second line for mobile data only. Your usual SIM stays in the phone for calls and texts, and WhatsApp, iMessage and other apps keep working with your own number.

### What happens if I run out of data?

Plans that support top-ups can be extended from your eSimNest account without installing a new eSIM. Whether a plan can be topped up is shown in its details. Otherwise you can buy a new plan at any time.

### Can I share the connection as a hotspot?

Most plans allow tethering. Plans marked with Hotspot in the list support it; check the plan details before you buy if it matters for your trip.

### How much does an eSIM for St. Lucia cost?

Plans for St. Lucia start at $1.56. For a week-long trip with everyday use (about 1 GB a day), the cheapest plan is $40.32: 1 GB a day for 7 days.

### Is there an unlimited eSIM for St. Lucia?

Yes, 3 plans have unlimited data, from $3.70. Unlimited plans usually slow down after a daily high-speed allowance; each plan's details state the policy.

### How long is an eSIM for St. Lucia valid?

Fixed plans are valid for 7 to 30 days from activation, and daily plans can be bought for 1 to 30 days.

### Does the eSIM work on 5G in St. Lucia?

The plans for St. Lucia use 4G/LTE networks.

### Can I make calls and send SMS with an eSIM in St. Lucia?

eSIMs for St. Lucia are data-only. You can still call and message over the internet with apps such as WhatsApp or FaceTime.

### Is a regional plan cheaper than a St. Lucia plan?

Regional plans that include St. Lucia cost a typical $5.02 per GB, against $5.00 for plans made for St. Lucia. A regional plan makes sense if you visit more than one country; for St. Lucia alone, compare both in the table.
