AlpineSIM eSIM Data Plans for South Korea

AlpineSIM does not provide a true unlimited data eSIM for South Korea; all available plans list a specific data allowance such as 500 MB, 1 GB or 2 GB per day. The “Unlimited” name used in some product titles refers to a fixed high‑speed data allocation, after which the speed may be reduced or the plan expires.

If you need a larger data budget, AlpineSIM offers fixed‑data plans. For example, the South Korea eSIM – 50 GB plan is valid for 30 days, and the South Korea eSIM – 20 GB plan also has a 30‑day validity. Both plans provide 5G connectivity and allow tethering. These fixed data options may be more cost‑effective for travelers who expect to use a significant amount of data.

AlpineSIM does not offer an eSIM plan for South Korea that includes a phone number or SMS capability. The provider’s South Korea offerings are limited to data‑only plans.

Travelers who need to make voice calls or send text messages can use popular VoIP applications—such as WhatsApp, Telegram, or iMessage—over the data connection provided by the eSIM.

AlpineSIM’s overall catalogue includes 9 single‑country data plans and 140 multi‑country data plans. The data summary does not provide a country‑specific breakdown, so the exact number of AlpineSIM plans that are available for South Korea cannot be determined from this information alone. The plans that are listed vary in price from $0.42 to $258.50, offer data caps from 100 MB to 50 GB, and have validity periods ranging from 1 to 365 days. If you need the precise count for South Korea, reviewing the provider’s detailed plan list or contacting their support would be necessary.
