100 Dumb US Laws (With Proof They Exist)
Calls and text messages from abroad have largely been replaced by apps like WhatsApp, Messenger, or FaceTime. For internet access in the USA, getting a local eSIM or SIM card is usually the best value. However, it is still important to activate roaming before you travel so you remain reachable on your home number, for example, for incoming banking verification SMS. In this article, you will find an up-to-date overview of prices for calls, data, and texts from the USA to the UK, Ireland, Australia, and New Zealand.

What You Need to Know About Roaming in the USA
Turn Off Data Roaming Before You Fly
Before boarding the plane, I strongly recommend turning off data roaming in your phone settings. This ensures your phone doesn’t automatically connect to mobile internet upon arrival, preventing you from being charged exorbitant fees based on your operator’s standard price list.
- Android: Go to Settings – Connections – Mobile Networks and toggle Data Roaming to the off position.
- Apple (iOS): Open Settings, select Cellular (or Mobile Data) – Cellular Data Options. Turn off the Data Roaming switch here.
VoLTE Support and Signal Coverage
The older 3G network has been completely shut down in the USA. To make calls, it is essential that your phone supports VoLTE (Voice over LTE) and that you have it enabled in your settings. Without VoLTE, you will not be able to make calls with most phones in the USA, not even to emergency services. 4G/5G mobile signal is available in most areas, though “dead zones” can occur in remote parts of national parks or deserts. You can find a coverage map on the Federal Communications Commission (FCC) website.
How to Get Cheap Mobile Data in the USA
The most convenient way to get data is through the Airalo app. You can simply purchase a data eSIM from the comfort of your home. The advantage is that the internet works immediately upon arrival; you don’t have to search for an operator’s store or physically change your SIM card, eliminating the risk of losing it.
How to Activate Roaming?
If you are traveling abroad for the first time or are unsure about your settings, check your roaming activation in your operator’s app or online portal. You can usually handle everything online within a few minutes. Most major carriers in the UK, Ireland, Australia, and New Zealand enable roaming by default, but it is always safer to verify this before departure. -
Roaming for UK and Irish Travelers
Since Brexit, roaming rules have shifted for UK citizens, while Irish citizens still enjoy EU roaming benefits—however, the USA falls outside EU zones for everyone. This means “Roam Like at Home” does not apply.
⚪ United Kingdom (Vodafone, O2, EE, Three)
Most major UK networks now charge a daily fee to use your home allowance in the USA.
- Daily Roaming Fees: Expect to pay around £5.00 to £7.00 per day to access your domestic data and minutes.
- Fair Use Limits: Even if you pay the daily fee, data is often capped (e.g., at 25GB or 50GB per month) to prevent excessive usage.
- Pay As You Go: If you do not have a bundle, standard rates are extremely high. Data can cost as much as $6 per MB.
⚪ Ireland (Vodafone, Three, Eir)
Irish carriers classify the USA as a “Rest of World” zone.
- Red Roaming / Day Passes: Carriers like Vodafone IE offer a daily roaming fee (typically around €3.99 to €4.99 per day) to use your home plan.
- Bill Shock Protection: Irish operators are required to send you a warning SMS when your data usage reaches a certain cost limit (usually around €50), but it is best to rely on a prepaid pass or eSIM to avoid reaching this point.

Roaming for Australian Travelers
Australian operators generally classify the USA as a Zone 2 or “Zone A” country, meaning it is included in most travel pass options, but pay-as-you-go rates remain high.
⚪ Daily Roaming Packs ($5 – $10 AUD)
The three major networks (Telstra, Optus, Vodafone AU) all offer a version of a “Day Pass.”
- Telstra & Optus: Usually charge $10 AUD per day for an International Day Pass, which gives you unlimited talk/text and a modest data allowance (often 1GB – 5GB per day).
- Vodafone AU: Offers “$5 Roaming,” allowing you to use your home plan inclusions for just $5 AUD extra per day. This is widely considered the best value for Australians using their own number.
⚪ Pay As You Go Rates
Without a pack active, costs are prohibitive. Calls can cost upwards of $2.00 – $4.00 AUD per minute, and data is charged at premium rates. Always ensure your “International Day Pass” or equivalent is active before turning on data roaming.

Roaming for New Zealand Travelers
For Kiwis, the USA is a popular destination, and local operators have structured their roaming packs to be relatively simple to use.
⚪ Daily Roaming ($8 NZD)
One NZ (formerly Vodafone) and 2degrees typically offer a flat daily rate of $8 NZD.
This fee allows you to use your plan’s minutes, texts, and data as if you were in New Zealand. There is usually no need to buy a separate bundle; the fee triggers automatically when you use your phone.⚪ Spark Roaming Packs
Spark generally operates on a “Roaming Pack” system rather than a daily automatic charge. You can buy packs valid for 7 or 14 days (e.g., roughly $20 – $30 NZD) which include a set amount of data and minutes.
If you do not buy a pack, casual rates apply: Data can cost over $10 NZD per MB, so purchasing a pack or using a travel eSIM is highly recommended.
