There are absolutely other carriers that are slightly better price (but I would argue not value) depending on what you need. If you don’t need wifi calling, that opens the door to a couple of carriers, if you don’t need unlimited calling/texting that opens the door, if you’re willing to pay for 6 or 12 months in advance, that expands the choice, if you can live with native Sprint only (no roaming) some other options appear, etc etc.
As an idea of costs, the only other “refund” player in the market is Fi. They have very limited phone selection and their talk/text plan starts at $20 and data is then $10GB over that. So no data is as expensive as Republic’s 1GB plan.
People tend to forget what they get with Republic. Unlimited Calling/Texting, robust wifi calling, call/text roaming, MMS that does not count against your data and be used on a no data plan, Republic Anywhere… These are all highly uncommon in the “cheap” plan space.
Other major players, including Cricket, MetroPCS and T-Mobile have unlimited talk/text at $25 with no data and often no MMS at all.
