There are two main options: eSIM kits (digital SIMs with no physical card) and physical SIM kits. Physical kits often include a 3-in-1 SIM that fits nano, micro and standard sizes in a single card.
Physical SIM kits typically include a 3-in-1 SIM that provides Nano, Micro and Standard sizes from a single card.
eSIM kits are usually activated by scanning the scannable QR code included with the kit and following the on-device prompts to install the eSIM profile.
eSIM kits require an eSIM-compatible phone or tablet. Physical SIMs require a compatible (and often unlocked) device that accepts the SIM size. To access 5G service you also need a 5G-capable device and 5G network coverage.
Service plans are generally sold separately or vary by rate plan. Active service or pairing the SIM/eSIM with a plan is required to complete activation and use the service.
Many kits list their expiration as "Does Not Expire," indicating no expiration date is provided in the available details.
Activation guidance commonly includes visiting the carrier's activation webpage or app, following on-device prompts or a text link, and contacting the carrier's support phone number when provided.
