Antwort auf „Verizon vs AT&T sim card”Actually, there is zero misinformation. The Verizon iPad will work on most GSM carriers including AT&T. The AT&T iPad does not have the antennae set up to work on CDMA. So they are not the same. As well as the LTE (which was my original statement) bands being entirely separate, and non-interoperable they're both in the 700mhz band but are still different frequencies. The iPads are different. Do they have the same Qualcomm chip? Yes, so the antennae are the "same". But they have separate operating parameters. Wi-Fi + 4G for AT&T 4G LTE (700, 2100 MHz); UMTS/HSPA/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz) Wi-Fi + 4G for Verizon 4G LTE (700 MHz); CDMA EV-DO Rev. A (800, 1900 MHz); UMTS/HSPA/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz) (source: apple.com)
Antwort auf „Verizon vs AT&T sim card”The antennae are different between the two. AT&T and Verizon each use different bands for their LTE networks. The iPads are outfitted for each carrier to match.
