If you have an iPhone older than the iPhone 8 you should consider the new iPhone SE. It has the same processor as the iPhone 11 Pro but with a smaller size if you don’t need a really large phone. It has Wi‑Fi 6 and Gigabit‑class LTE to deliver much faster download speeds, whether you’re on Wi‑Fi or cellular networks. It supports two SIM cards and two phone numbers.
