Apple’s support for dual SIM, dual standby (DSDS) on this year’s iPhone generation was a double-edged sword. On the one hand, it finally gave what some iPhone owners have been requesting for years. On the other than, its implementation is based on a normal, physical SIM and a digital eSIM. The latter requires carriers to support the feature and as of yesterday, only AT&T does in the US. That, however, is changing soon with both Verizon and T-Mobile following not far behind.
