For travelers, this means: activate a data plan before you leave home, no need to find a SIM card shop upon arrival, switch between providers without physical card swaps, and manage multiple profiles on a single device.
The technology is supported by most smartphones released after 2018, though compatibility varies by manufacturer and regional device variant. Our FAQ section provides detailed device compatibility information.
