Flashing an LG 840G Tracfone to use with a T-Mobile SIM card typically involves unlocking the device and installing compatible firmware. First, ensure your phone is unlocked by contacting Tracfone or using a third-party service if necessary. Then, you may need to find and install a custom ROM or firmware that supports T-Mobile's network bands. Note that flashing may void warranties and can potentially damage your device, so proceed with caution and follow detailed guides specific to your phone model.

If you have a tracfone do you have to get a tracfone card or can you get any other card for a tracfone?

When you are getting any sort of mobile prepayed phone it is usually the case that it will only take a card for that specific provider. Like Virgin Mobile only takes their own cards and AT&T Prepayed only takes their own cards as well. But there are a few places, like walmart for instance, that do provide universal cards that work with any prepayed mobile provider out there like alltel, at&t, virginmobile, verizon, tmobile, tracfone, etc. These universal cards MIGHT also be at radioshack considering radioshacks have a pretty wide variety of cell phone and pre payed phone cards and what not.

Which Tracfone models have the T5 sim cards and which have the C4 sim cards?

The C4 sim card shows that ATT is the carrier for that certain phone. The T5 sim card shows that T-Mobile is the carrier for that phone. Tracfone borrows from other carriers to provide their service. If the tracfone has a C4 sim card then there will be a P4 at the end of the model number. If the tracfone has a T5 sim card then there will be a P5 at the end of the model number.
