TracFone-based Verizon MVNOs are currently enjoying unthrottled speeds. Although this is not an official report, sources say that they have been able to enjoy much faster LTE speeds compared to the ones that they are originally restricted to.
Earlier, BestMVNO reported on how this has affected subscribers under TracFone-based Verizon MVNOs like Straight Talk and Total Wireless. A more recent addition to this is Page Plus Cellular, whom the subscribers are sharing that they received a text message notifying them of increased speeds. To further confirm these text messages, Page Plus has launched a subdomain on their website pertaining to this change.
As of this writing, there has been no official announcement whether or not the speed cap has been lifted across all MVNOs under Verizon or just the ones under TracFone's. We'll have to wait for more updates on this matter to confirm anything.
