You get home from a trip or the first month of living abroad and open your phone bill. The number you see is not what you expected. It might be 150 euros. It might be 400 euros. In extreme cases, it might be over 1,000 euros. International roaming charges have a way of appearing on phone bills like an ambush — and the worst part is that the data you paid that price for was probably slow, throttled, and frustrating to use.

If this has happened to you, or if you’re heading abroad and want to make sure it never does, this post is the complete fix. We’ll explain exactly why roaming charges are so expensive — the mechanisms behind the charges — and give you the permanent alternatives.

How Roaming Charges Actually Work

When you use your phone in a foreign country, your home carrier has to pay the local carrier a wholesale fee for access to their network. Your home carrier then charges you a retail rate with their margin added. The specific charges on your bill can come from several sources: daily roaming add-on fees (a fixed charge per day your phone connects abroad), per-MB data charges, per-minute call charges, and per-message charges. Many people accumulate charges from all four categories simultaneously without realising it.

The Real Cost of Roaming: Examples

A UK traveller using their home plan in the US: typically 5-15 GBP per day for a daily roaming add-on. A week in the US: 35-105 GBP. A German traveller in Turkey: 1.99-9.99 euros per day. A month: 60-300 euros. A student from Brazil in Portugal without an EU plan: roaming rates can exceed 10 euros per day easily. Three months: over 900 euros. These are real numbers that real people pay because they did not know the alternatives.

Why Roaming Packages from Your Carrier Are Still Expensive

Many carriers offer international roaming add-ons — a daily or weekly fee that gives you a limited data allowance abroad at a fixed rate. These are better than uncontrolled roaming charges, but they’re still expensive compared to local alternatives. A 10 GBP per day roaming add-on in the US gives you perhaps 500MB of data. A ConnectPls eSIM for the US gives you multiple GB per day for a fraction of that price.

The Permanent Fix: How to Stop High Bills Abroad Forever

The fix is a two-step process. Step 1: Turn off roaming on your home carrier SIM permanently when abroad. Settings — Mobile — Cellular — Roaming — Off. With roaming disabled, your home SIM cannot generate roaming charges regardless of what country you’re in. Step 2: Use a ConnectPls eSIM or SIM card for data in your destination country. Local data, local prices, no carrier markup.

With these two steps in place, you physically cannot receive a surprise international roaming bill — because your home carrier SIM is not being used for data. Your calls and texts through your home number still work over WiFi (WhatsApp, iMessage, FaceTime) without roaming charges.

What to Do Right Now If You’re Already Abroad and Getting Charged

If you’re currently abroad and already racking up roaming charges, the fix is immediate. First, turn off mobile data roaming in your phone settings. This stops further charges from your home carrier immediately. Second, connect to WiFi wherever available. Third, purchase and activate a ConnectPls eSIM — takes about 10 minutes — and turn on mobile data using the eSIM line. Your roaming charges stop the moment you switch data lines.
