Hey everyone,

Instead of guessing which local carriers Saily hooks up to around the world, let's build an unofficial, crowdsourced master list for the community!

If you look at Saily's official site—whether it's for the United States, Europe, or anywhere else—they generally just promise a "reliable connection from the best networks" without actually naming the providers.

If you've used Saily anywhere in the world, please drop a comment below with:

The Country you were in (or are currently in!)

The Local Network your phone actually connected to (e.g., T-Mobile, Vodafone, Telstra, Orange, etc.)

Your general location & speeds (if you remember!)

I'm personally trying to figure out the exact carrier situation for the USA right now before I use it there, but it would be amazing to get a global database going for everyone planning their travels.

Let's map this out! Who are they actually

Hi everyone!

A lot of people only notice data roaming after getting an unexpectedly high phone bill abroad.

In simple terms, data roaming is when your phone connects to a foreign mobile network outside your carrier’s normal coverage area. That’s what allows you to use maps, social media, email, or streaming while traveling internationally.

The convenient part is that it usually works automatically the moment you land. The downside? Roaming charges can add up very quickly - especially for things like video streaming, navigation apps, or background syncing.

One thing many travelers overlook is that apps can keep using data even when your phone is idle. Automatic updates, cloud backups, and background refreshes all contribute to roaming usage.

A few common ways people reduce roaming costs:

• Use Wi-Fi whenever possible
• Turn off background app refresh
• Monitor data usage in phone settings
• Disable roaming when not needed

More travelers are also moving toward alternatives like eSIMs instead of traditional roaming. Services like Saily eSIM let users activate travel data plans digitally before arriving, which is often cheaper and easier than pay-per-MB roaming.

Interesting difference globally: within the EU, roaming is usually treated like domestic usage for EU SIM cards, while many US carriers still rely on daily roaming fees or expensive per-MB pricing.

What do you usually use abroad - traditional roaming, local SIMs, or eSIMs?

Travelling with my spouse to Europe so decided to go with Saily. Bought 2 eSIMs but their process makes it very challenging to install onto 2 iphones. Better off buying one at a time.

Data works in Beijing but you can't get two-factor authentication messages which means that you can't, Make payments through alipay, or get around via didi, which means you can't really exist here in Beijing.

This is not a customer support query, this is a warning to other potential users.
