The table below compares regular fixed-data plans. It does not include coupon codes.

esimNB offers 1GB to 50GB plans and connects through Verizon and AT&T. Its current prices range from $2 for 1GB to $56.50 for 50GB. The 20GB plan costs $23.50, or about $1.18 per GB.

Network coverage comparison

1. esimNB

esimNB lists both Verizon and AT&T for its USA plans. It also states that the plans use a direct US IP address and support 4G and 5G.

This is useful for travelers moving between cities, suburbs, and less populated areas. However, actual coverage still depends on your location, phone, signal strength, and the network available to the plan.

2. Airalo

Airalo shows T-Mobile as its main USA network, with one additional network available on the displayed product. The exact network can depend on the plan you select.

Always open the plan details before paying. Do not assume every Airalo USA plan has access to every network.

3. Saily

Saily promises access through local US partner networks, but its main product page does not clearly name the networks for every plan. It supports 3G, 4G, LTE, and 5G where available.

4. Nomad

Nomad clearly lists T-Mobile, AT&T, and Verizon. Some plans can use more than one network, allowing users to switch if another supported network has better coverage.

This makes Nomad a good choice for road trips or visits outside large cities. Check the individual plan because network access may differ between products.

5. Sim Local

Sim Local sells plans from several providers, including Sim Local, Lycamobile US, and Three UK. The network and features depend on the product. Some plans are data-only, while others include calls and SMS. If you are also considering a physical SIM, our USA tourist SIM card guide covers local prepaid options and where to buy them.

Hotspot and laptop use

All five providers have plans that support hotspot use, but fair-use rules still matter.

• esimNB: Suitable for sharing fixed data with a laptop or another phone.
• Airalo: Hotspot normally works, but unlimited-plan limits still apply.
• Saily: States that it has no hotspot restrictions.
• Nomad: Supports hotspot on its USA plans, subject to plan limits.
• Sim Local: Supports sharing, but unlimited plans slow down after the daily high-speed amount is used.

For short periods of remote work, 10GB or 20GB of fixed data may be enough. For daily video meetings, cloud uploads, or streaming, Sim Local’s 10GB-per-day plan offers more room.

Extra features

Saily is the strongest choice for built-in privacy tools. Its app includes features designed to block ads, reduce trackers, and protect browsing.

Airalo is useful for travelers who want a large, mature platform. It supports many languages, top-ups, automatic renewal, and 24/7 multilingual support.

Which USA eSIM should you choose when travelling from Australia?

For a one- or two-week US trip, we recommend esimNB’s 10GB, 30-day plan at US$12.50 if you mainly need data for maps, Uber, messaging and everyday browsing. Choose 20GB for US$23.50 if you expect heavier use.

Here’s what makes it a practical choice before leaving Australia:

• Buy before departure: validity starts when you first connect in the destination, so purchasing early won’t use up your travel days.
• US network access: the plans list AT&T and Verizon as supported networks.
• Hotspot support: share your data with a laptop or another device.
• Enough validity for a longer holiday: both plans last 30 days, covering a two-week trip without needing a second package.

These prices are in US dollars, not Australian dollars; your final AUD cost depends on the exchange rate and any payment-provider fees.

Which USA eSIM is best for different types of travelers?

Is esimNB cheaper than roaming with your Australian provider?

If you are unfamiliar with how data roaming works, start with the basics before comparing your Australian plan with a travel eSIM.

Daily roaming charges add up on a two-week US holiday. Here’s the extra cost if you use roaming every day:

Rates checked 8 September 2026. Carrier offers require eligible plans; totals exclude your regular Australian plan fee and extra usage charges. esimNB is priced in USD, with the final AUD amount depending on conversion and payment fees.

If 10GB covers your trip and you mainly use messaging apps, esimNB is a lower-cost choice. Australian roaming packages include calls and texts, so they may suit you better if you regularly need to make or answer calls on your Australian number. Optus can trigger another A$5 pass when you exhaust its 5GB allowance, even within 24 hours.

Can you keep your Australian number for bank verification codes?

Yes—on a compatible dual-SIM phone, you can use esimNB for US data while keeping your Australian line active for SMS. Your Australian service must support roaming in the USA; verification-code delivery still depends on your bank and carrier.

Receiving an SMS alone does not trigger a Telstra International Day Pass or Vodafone’s $5 Roaming fee.

If you have not added your travel line yet, follow our guide to installing and activating an eSIM on iPhone before departure. Once it is installed, use these settings:

• Mobile Data: select your esimNB line.
• Australian line: keep it on, but turn Data Roaming off.
• esimNB line: enable Data Roaming as instructed.
• Allow Mobile Data Switching: turn it off to keep data on your travel line.

Apple explains these controls in its dual-SIM guide.

Turning off data roaming does not prevent call or outgoing SMS charges. Making or answering regular calls, or sending texts on your Australian line, can still trigger roaming fees. Use WhatsApp or other internet calling apps over esimNB data when practical.
