The carrier now supports DIY line activation technology on Apple’s 2018 iPhones — but only for prepaid plans.

Following in the footsteps of AT&T and VerizonT-Mobile now supports Apple’seSIM technology, which lets customers activate a phone plan remotely and maintain two active lines simultaneously.

T-Mobile customers can now activate a second line on the iPhone XSiPhone XS Max or iPhone XR through the T-Mobile eSIM app. They’re restricted to one of three prepaid phone service plans, however:

  • T-Mobile ONE Prepaid: includes 30 days of unlimited voice, text, and data for $70
  • Simply Prepaid: includes 30 days of unlimited voice, text, and 10GB of LTE data for $40
  • Tourist Plan: includes 21 days with 1000 minutes of voice, text, and 2GB of LTE data for $30

T-Mobile customers looking to add a primary or family plan, or activate a second postpaid line on one phone, will have to go to one of the company’s retail locations or use its DIGITS service, which allows up to five lines on one device.

eSIM is the software-based version of the traditional plastic chip that identifies you to your carrier. Apple’s iOS 12.1 update enabled the feature for the iPhone XS, XS Max, and XR in October. After encountering technical issues, including “degraded” service and problems linked to visual voicemail, AT&T and Verizon delayed their support for the feature.

With those issues apparently resolved, AT&T and Verizon launched support for eSIM earlier this month. Sprint has said that it will eventually support eSIM technology, but has not yet announced a timeframe.

Correction, 12:11 p.m. PT: An earlier version of this story had incorrect details for the Tourist plan based on information from T-Mobile. The Tourist Plan includes 1000 minutes of voice.
