At that time, we thought that only applies to the four postpaid plans which were known as the Value Plans. As it turned out, the same goes for the Ultimate Plan as well, based on several screenshots that were shared by Twitter user @aniq8676 which depicted several conversations with Unifi customer service:
— NIQ (@aniq8676) February 18, 2023 In order to use 5G starting from March 2023 onwards, Unifi Mobile customers have to subscribe to any of the three new UNI5G plan instead which is something that has been confirmed by TM’s representatives to Lowyat.NET. This is because the current unlimited 5G pass for the Ultimate plan is only valid until the end of February 2023. For those who want to obtain the same service level as per Ultimate plan which has unlimited data and calls as well as 10GB of hotspot data, they have to sign up for the UNI5G 89 plan. Unlike its predecessor though, the UNI5G 89 customers have to pay for SMS though at a rate of 15 sen per SMS.
