International roaming charges can turn a dream holiday into a bill shock nightmare. Here's how to stay connected in 190+ countries without paying your home carrier's extortionate roaming rates.
Why roaming fees are so expensive
When you use your home SIM abroad, your carrier connects to a partner network in that country and charges you a premium for the privilege. These rates are often 10–50x what locals pay for the same data. A single day of roaming in some countries can cost more than an entire month's local plan.
Option 1: Buy a local SIM card
The traditional solution. You swap your home SIM for a local one on arrival. It's cheap but comes with downsides — you lose access to your home number, you need to physically find a SIM shop, and you're juggling multiple cards across a trip.
Option 2: Use an eSIM (recommended)
An eSIM gives you a local data plan without replacing your home SIM. You keep your home number active for calls and messages, while using the eSIM for data at local rates. Plans start from $2 and the QR code is delivered to your email instantly.
How to set it up:
- Buy a plan at instantesims.com before you travel
- Scan the QR code to install the eSIM
- Land, connect, and save
Option 3: Pocket Wi-Fi device
A portable Wi-Fi hotspot that connects to local networks and creates its own Wi-Fi signal for your devices. Works well for families or groups. Downside: it's another device to charge and carry.
Option 4: International roaming add-on
Most carriers offer a daily or weekly international roaming pass. These are convenient but expensive compared to a local SIM or eSIM. Use only as a last resort.
The smart traveller's approach
Install an InstantESIMs eSIM before departure. You'll be connected before you've left the arrivals hall — and you'll never pay roaming fees again.
