Yeah I just done some research on QLink and their nationwide 4G-LTE/5G network. I must admit, I wish I could qualify for the service. Subscribers get a free smartphone (or they can use a compatible phone of their own per the BYOP program), free unlimited calling, texting and unlimited data (with no maximum cap for exceeding a set amount). The unlimited data is being provided as part of the Emergency Broadcast Benefit (EBB) approved by good old Uncle Sam. Normally, 4.5 GB of 4G-LTE/5G data per month is the allotted amount per subscriber. The nationwide network is Sprint, which is now owned, maintained and operated by T-Mobile per last year's acquisition and merger. In turn, QLink subscribers have the option of either T-Mobile's traditional nationwide GSM coverage or their CDMA nationwide coverage . Here's the real good part: QLink does not officially provide allotted data in its monthly data plans for mobile hotspot or tethering. However, a well-known loophole -- a simple tweak of the APN parameters - allows users to enjoy high-speed, fully unlimited 4G-LTE/5G mobile hotspot as well. Some QLink subscribers at XDA recently boasted using in excess of 500GB in a month! So yeah, I've got to find some poor soul who will sell me his/her SIM card. My biggest question is how on earth is QLink not detecting such an enormous consumption of data by subscribers? Then I got my answer: they have more to worry about. On June 9th earlier this year, dozens of agents from the US Postal Inspection Police, the FBI, the Department of Justice, the Internal Revenue Service and the Broward County Sheriff's Department raided QLink's corporate office in South Florida. Several crates and boxes of documents were seized by the agents. While the root of the investigation has been very tight-lipped, it is known that QLink is being investigated for federal wire fraud and defrauding the US government under the terms of a federal contract (Lifeline and the Emergency Broadband Benefit I am assuming).

So maybe I should hold up on trying to buy a SIM ??
