Roam Announced the Upcoming Premium eSIM: A Revolutionary All-in-One Solution for Global Connectivity

Vancouver, Canada, May 29, 2025

Roam announced its upcoming Premium eSIM at the Solana Accelerate: Ship or Die conference in New York. This new feature provides secure, high-speed mobile connectivity by combining data, voice, and SMS in a single eSIM. Accessible in over 160 countries, the Premium eSIM eliminates the need for physical SIM cards and roaming fees, offering a seamless global communication experience.

Roam Premium eSIM

The Premium eSIM represents the next evolution of Roam’s connectivity solutions, building on the success of the Roam Global eSIM, which offers data-only service. The Premium eSIM expands this by adding voice call and SMS capabilities, creating a complete communication solution for global travelers.

Users can now join the pre-sale registration for the Premium eSIM through the Roam App. To register, users must verify their email, complete KYC, and top up their account balance. These steps were demonstrated live at the Solana Accelerate event, showcasing just how easy it is to get started. The Premium eSIM will be officially launched and available in the coming days.

Key features of the Roam Premium eSIM include:

  • Austria-based Phone Number: Each user receives a +43 phone number for global calling and messaging.
  • Worldwide Coverage: Reliable service across 160+ countries and regions.
  • All-in-One eSIM: Access high-speed data, voice calls, and SMS in one eSIM.
  • No Physical SIM Required: Activate directly through the Roam App with just a few taps.
  • Zero Roaming Fees: Eliminates costly roaming charges for worry-free global travel.
  • Flexible Payment Options: Supports auto-recharges using credit cards, cryptocurrencies such as USDC, USDT, and $ROAM, plus upcoming local methods like WeChat Pay and Alipay.
  • Account Management: Track your balance and data usage through the Roam App for better control and transparency.

How to Activate Premium eSIM

Activating the Premium eSIM is a simple and straightforward process in the Roam App. Here’s how to do so in just five steps: 

Step 1: Download the Roam App (iOS or Android) and create an account.

Step 2: Top up the account with a minimum balance of $20

Step 3: Verify and link an email address. 

Step 4: Complete KYC verification (a $2 fee applies).

Step 5: Activate the Premium eSIM.

Existing Roam Global eSIM users can easily switch between the Global eSIM and Premium eSIM. Any remaining data will automatically transfer to the active eSIM. Please note that only one eSIM can be active at a time. 

Solana Attestation Service Integration

At the conference, Roam also announced its integration with the Solana Attestation Service (SAS), making it one of the first projects to adopt this decentralized identity verification and trust certification system. Built on the Solana blockchain, SAS is a new open source, permissionless protocol to attest to anything – the trust layer for internet capital markets. 

Pushing Boundaries 

The integration with the Solana Attestation Service and the new Premium eSIM elevates Roam’s capabilities from global connectivity to breaking barriers in telecom accessibility through Solana. Moving forward, Roam will continue collaborating with more Web3 and Web2 companies, along with multinational organizations, to revolutionize global connectivity and redefine how people stay connected.
