#1. Game-changing mobile service that delivers unbeatable mobile reliability

Only with Pronto do you get access to the big three nationwide carriers plus many of the smaller regional providers – with automatic, real-time switching to the best available connection.

And, rest assured, Pronto provides full access to every major carrier's 5G networks plus their legacy networks.

#2. Real value, real transparency, real people offering responsive service

At Pronto, we're on a mission to end hit-or-miss mobile—and here's the best part—we want to earn your business each and every month. That's why we offer:

15-Day free trial—no risk, no obligation (seriously!)
Value-packed, no-contract, competitive plans—each with access to the big 3 carriers and unlimited switching to best available connection
Making it Right—Customer Satisfaction Guarantee (we put our money where our mouth is)
Customer Give and Get Referral Program—More details coming soon

An eSIM is your phone's built-in digital SIM—no more fiddling with tiny plastic chips and paperclips! It works like a physical SIM, connecting you to mobile service, but lives entirely in your device. At Pronto, we use eSIMs for fast, easy setup—no stores, no waiting.

Probably, but let’s make sure. There are two requirements:

#1. You need an unlocked phone.

Here’s how to check to see if your phone is locked:

On iPhone: Go to Setting > General > About. Scroll down to Carrier Lock. If it says No SIM restrictions, your phone is unlocked. If it mentions a carrier, the phone is locked.

On Other Phones: Open the phone dialer and call *#06#. Your phone IMEI will appear on your screen. Enter your IMEI in a credible IMEI-checker site, like IMEI.org or IMEI24.info, to see if the phone is unlocked.

#2. You need a phone with eSIM support.

iPhone 11+, Samsung S20+ and most other recent model phones support eSIM.

Not sure about your phone? Open the phone dialer, then call *#06# — if you see an EID number, your phone supports eSIM.

If you’d like to use two phone plans (e.g., during your Pronto trial), open the phone dialer, then call *#06#. If you see two IMEI numbers, you’re set if you have an iPhone 13+ and Samsung S24. For earlier models that offer one eSIM and one physical SIM, Pronto will require the eSIM spot.

If only one appears, Pronto will become your primary service (an excellent choice!).

If you purchased your phone from a carrier, it might be locked. If your phone is locked, unless under contractual commitment, your carrier must unlock your phone. For Verizon customers, your phone must be unlocked by Verizon 60 days after purchase.

AT&T: 800-335-4685
T-Mobile: 1-800-937-8997
Verizon: 1-800-837-4966 (automatically unlocks phones after 60 days)
US Cellular: 800-766-9811

Your free Pronto trial includes incredible value: access to all major networks with real-time switching to the best available connection. We're serious about mobile reliability and want you to be, too. We're confident Pronto will deliver, so we collect payment details to welcome you seamlessly as a member if you love the service.

Not satisfied? Your trial remains completely free with no obligation. Cancel anytime through your account or by contacting us. We'll remind you 3 days before it ends.

If your phone offers dual eSIM support (most recent models do) you can keep your current plan while you try Pronto. You'll receive a Pronto phone for calling and texting using your Pronto trial account. As part of the simple set up, we'll show you how to move between your current carrier plan and Pronto, for voice/text and/or data. It's easy!

Love Pronto and want to stay? You can port your current phone number to Pronto or use your Pronto number. The choice is yours.

Even with Pronto, if none of our partner networks have a cellular signal where you are, there’s no connection—at least for now. We’re just getting started. Expect continued innovation, like satellite services, in the near future.

In the meantime, if you’re not connected, we’ll be constantly searching for a signal. The moment one’s available, Pronto will connect you—automatically.

And as part of our commitment to better mobile for everyone, we'll share insights on trouble zones with our partners to help improve coverage over time.

You're 5 minutes from Pronto!
