Guide
A free eSIM trial can help you check a carrier on your own phone before you switch. But a US network trial, recurring travel data and referral credits are different offers. Start with the phone requirements, payment rules and what happens when the offer ends.
The company pages below describe US carrier trials and travel eSIM offers. A free app download does not mean the data plan is free.
Checked Oct 2026 against official pages
T-Mobile's trial page offers up to 30 days while you keep your current carrier and phone number. You need an unlocked, compatible eSIM phone, existing service on another carrier and Wi-Fi for setup. T-Mobile directs you to the T-Life app. The trial is for participants in the United States, not international use.
Verizon's Free Trial page offers 30 days with no credit card, contract or credit check. You need an unlocked phone compatible with Verizon and an available eSIM slot. Verizon includes unlimited talk and texting, plus up to 100 GB of premium data. You keep your existing carrier service and number; Verizon supplies a temporary trial number.
Visible's Free Trial page offers 15 days with no credit card, contract or auto-renewal. You need an eSIM-capable phone compatible with Visible and must be in the United States. Visible checks your device, then asks for your name, email and zip code. Its page says you receive a trial number without affecting your current number or service.
US Mobile's trial information says you must add a valid credit card to start its 30-day free eSIM trial. US Mobile says you are not charged during those 30 days. This differs from Verizon and Visible, which explicitly say no credit card is required.
AT&T's trial information offers 30 days of free wireless-network testing through eSIM. AT&T limits the trial to iPhone.
Google Fi's trial information offers a seven-day free trial. Its page also warns of a move to the Simply Unlimited plan at $50 USD per month and loss of access to your current service. Read the trial's ending conditions before you start.
Saily's page says its app is free to download, but its eSIM plans are not free. Its referral program gives your friend a discount and gives you matching Saily credits: US$5.00 for standard plans or US$10.00 for Ultra. You can use earned credits to buy travel eSIM plans. This is a referral offer, not an unconditional data trial.
Holafly's page explicitly says it does not offer a free trial. Instead, Holafly offers Always On, with 1 GB of recurring data per month for all Holafly eSIM users. Keep that distinction in mind when comparing it with a time-limited carrier trial.
The Saily, Airalo, Yesim and Ubigi pages we checked do not state a free trial. Saily describes referral credits; the other listed pages provide paid plan prices.
For a small paid plan, Saily lists Japan at 1 GB for 7 days for US$3.99. Yesim lists Japan at 1 GB for 30 days for US$4.44. These are paid alternatives, not free offers; prices checked Oct 2026.
Eligibility matters as much as trial length. T-Mobile states a limit of one trial per user and excludes anyone who participated in T-Mobile Trial, formerly Network Pass, in the last 6 months. Current T-Mobile, Metro by T-Mobile and customers of partners using T-Mobile's network are also excluded.
Verizon's Free Trial page excludes anyone who participated within the last year. Visible's page excludes current members, anyone who was a Visible member in the last 12 months and anyone who took its trial in the past 12 months.
Check the ending rule separately from the payment requirement. T-Mobile says its trial ends automatically after 30 days with nothing to cancel. Visible says there is no auto-renewal and you can end the trial at any time. US Mobile requires a card, while Google Fi warns about a move to a paid plan.
For Saily, installation and activation are separate. Saily says its plan activates when you arrive at your destination or 180 days after purchase. Its page also tells you to enable data roaming for the Saily eSIM.
Use the carrier's compatibility check rather than treating eSIM support alone as approval. Visible checks your device before signup. Verizon requires an unlocked, network-compatible phone with an available eSIM slot. Verizon says a phone without 5G compatibility can still try its LTE network.
T-Mobile's page gives this setup sequence. Once setup is complete, T-Mobile tells you to use its line as your primary SIM for data to test its network.
"From" is the lowest price we found on the provider's own destination pages (checked Oct 2026). Links go through our /go/ redirect; we may earn a commission.
Yes. Verizon's Free Trial page and Visible's Free Trial page both say no credit card is required. US Mobile says you must add a valid credit card, although it does not charge you during its 30-day trial.
T-Mobile, Verizon and Visible say you can keep your current number and service. Verizon and Visible provide a separate trial number. Visible's company page says the trial does not affect your current service.
Holafly's page says it does not offer a free trial. It offers Always On instead, with 1 GB of recurring data per month for all Holafly eSIM users.
Saily says the app is free to download, but its plans are not. Its referral program offers matching credits of US$5.00 for standard plans or US$10.00 for Ultra, which you can use to buy travel plans.
No. T-Mobile's trial page says it is only available to participants in the United States with existing service on another carrier and is not for international use.
