Simple Mobile, has posted on their Facebook Page "Starting Today! Giving you a bit more. How about 4G starting at $40?" The image gives the details, the first 250 MB of data per month will be delivered at full 4G HSPA+ speeds where available. After hitting the 250 MB threshold, speeds will be throttled to approximately 240 Kbps. The slower speed data is advertised as unlimited, but users have reported that after using about 3 GB their data is shut off for the remainder of the plan month. Before today all data use on the $40 plan was throttled to 240 Kbps.
Simple runs on the T-Mobile network which offers HSPA+ 4G in most major cities. T-Mobile's HSPA+ is fast, with a theoretical top speed of 42 Mbps and real world speeds running between 2 and 10 Mbps.
The Simple $40 plan was already a good deal and this change makes it even better. In addition to data, it also includes unlimited voice minutes and unlimited text messaging, including international texting. The throttled speed is quite usable too. The only downside with Simple is that it's limited to T-Mobile native coverage (map) which is quite limited compared with AT&T or Verizon. Also, outside of cities, much of T-Mobile's network is 2G only.
Simple Mobile is a SIM only operator. SIMs cost $12.99 on the Simple Mobile site but are available for under a dollar with free shipping on Amazon. A T-Mobile USA or unlocked GSM phone with support for the 1900 Mhz band is required. T-Mobile's 3G and 4G service is mostly on the 1700 Mhz but T-Mobile is starting to offer 3G/4G on iPhone and unlocked AT&T phone friendly 1900 Mhz in some areas (map).
