Budget Mobile (MVNO / 알뜰폰)

Budget mobile (알뜰폰) refers to the plans of operators that lease mobile networks to provide mobile phone service. You should compare plans, network, data, voice/text, promotion period, contract terms/early termination fees, USIM/eSIM, and customer center conditions on MVNO Hub (알뜰폰허브) and each operator's official site.

• Network used: Confirm whether it is the SKT network, KT network, or LG U+ network.
• Price: Break down the first month / promotion period / monthly fee after the promotion ends.
• Data: Check the basic allowance, speed after it runs out, and whether tethering/sharing is possible.
• Voice/text: Check the basic allowance, premium calls, and international call conditions.
• Sign-up method: Check the conditions for online application, USIM delivery, convenience store USIM, number porting, and new sign-up.
• Identity verification: Separately confirm whether PASS/mobile identity verification actually works on services that require it after sign-up.
• Customer support: Check the procedures for loss, name (ownership) change, cancellation, number porting, overseas roaming, and eSIM reissuance.

• Do not state definitively that "budget mobile is always cheaper" or that "the call quality is identical."
• Do not sign up based only on the promotional price; check the fee after the discount ends and the cancellation terms.
• Even if you bought the USIM at a convenience store, complete activation through the official operator's procedure.
• Do not use a line that is not under your own name or use proxy activation.
• If you suspect an unknown line has been activated, check the M-Safer (명의도용방지서비스) sign-up status inquiry (가입사실현황조회) and your carrier's customer center.

• "Please recommend the cheapest budget mobile."
• "With budget mobile, does identity verification always work?"
• "Will it still be cheap after this promotion ends?"
• "Can foreigners activate immediately online too?"

Because plans and identity-verification conditions change frequently, guide the above questions to the official comparison screen and the operator's customer center for confirmation.
