Normally, when Apple releases a new iPhone we United States, it only sells models linked to operators. However, for a long time, customers can simply walk into the store and choose to buy these devices at a “full price” (“Full price”). Thus, even if the device comes with the operator’s chip, it is completely unlocked.
Shortly thereafter, however, Apple always starts selling the SIM-free. This option is nothing more than a model totally disconnected from operators, bringing in its box even that SIM card ejection tool.
Interestingly, in the iPhone XS, Apple offered this model already at launch, along with options linked to the four largest operators in the country (AT&T, T-Mobile, Verizon and Sprint). This did not happen with the iPhone XR, which until now was sold only with chips from such operators; now, that has changed.
Those who enter an Apple store or buy the device online can now opt for the SIM-free. It is good to make it clear that, this year, there is absolutely nothing different about these models besides the fact that they come without an operator chip and with the SIM card ejection tool. We are talking about the same models (A1920, A1921 and A1984 – XS, XS Max and XR, respectively), which * do not * have support for the band 28 (700MHz APT) – in Brazil, Apple sells the models A2097, A2101 and A2105, as we already reported.
To summarize: in practice, it makes no difference to choose the AT&T, T-Mobile, Verizon, Sprint models – as long as you pay the “full price”, without being linked to such operators – or SIM-free. The only thing that changes is, as we said, the inclusion of the chip ejection tool and the absence of the operator’s chip in the tray. ?
