AT&T Mobility, Sprint, T-Mobile US and UK operator EE support a new SIM card for Apple’s iPad Air 2 and iPad mini 3 that lets customers switch between carriers. With an unlocked phone or tablet you can change your service provider by changing the SIM card, but with Apple’s new SIM card, you won’t need to buy a second (or third) SIM card.
Apple’s SIM card enables customers to easily switch service to a different carrier. As GigaOM notes, it’s unclear how the provisioning process will work if customers want to switch between carriers. While Verizon Wireless will provide wireless service for Apple’s new tablet, it is not listed as a supporter of the new Apple SIM card, notes Fierce Wireless.
“The new Apple SIM is preinstalled on iPad Air 2 with Wi-Fi + Cellular models,” Apple explains. “The Apple SIM gives you the flexibility to choose from a variety of short-term plans from select carriers in the U.S. and UK right on your iPad. So whenever you need it, you can choose the plan that works best for you–with no long-term commitments. And when you travel, you may also be able to choose a data plan from a local carrier for the duration of your trip.”
The Subscriber Identity Module stores your International Mobile Subscriber Identity number (IMSI), which is a unique serial number (ICCID), along with security and network data, your PIN, and a personal unblocking code. The SIM allows you to connect to the network and identifies you.
The International Mobile Station Equipment Identity number (IMEI), on the other hand, is on the phone itself and identifies the device. It’s like a VIN number on a vehicle and can be used for stopping a stolen phone from accessing the network by calling a network provider to “blacklist” the phone using its IMEI number.
[The Stingray is a brand name of an IMSI/ESN catcher sold to law enforcement. Burner phones (prepaid phones) aren't untraceable but don't require the user’s personal data at the point of sale or by the service provider. The NSA often locates drone targets by analyzing the activity of a SIM card, rather than the actual content of the calls, according to Glenn Greenwald. Makes you wonder if (or how many) people have been killed because they picked up a discarded phone that was interrogated by an IMSI Catcher on a Drone. ]
It’s easy to see how a SIM that supports multiple carriers simultaneously could disrupt the mobile industry, says Dan Frommer.
“Imagine booting up your iPhone for the first time and seeing four competing offers for your business from different operators—with short or no contract duration.”
The Pad Air 2 delivers faster connectivity with 802.11ac Wi-Fi with Multiple-In-Multiple-Out (MIMO) at data rates up to 866 Mbps. iPad Air 2 with Wi-Fi + Cellular integrates even more LTE bands and comes with expanded LTE for up to 50 percent faster cellular connections, plus support for Dual Carrier HSDPA (for carrier aggregation in the downlink) and HSDPA+ (with MIMO).
The iPad Air 2 has full support of most LTE bands.
But Apple’s iPad Mini 3 page shows only support for LTE bands 1, 2, 3, 4, 5, 7, 8, 13, 17, 18, 19, 20, 25, and 26, but not Sprint’s band 41.
The new iPad mini 3 is powered by the Apple-designed A7 chip and M7 motion processor compared to the newer A8X and M8 chips incorporated into the iPad Air 2 as well as a similar A8 chip in the iPhone 6 and 6+ which support Band 41 (2.5 GHz) for LTE on Sprint, as well as China and elsewhere.
Clearly, if Apple hopes to move many iPad minis in the Chinese market, they will need Band 41 support (and perhaps an A8X chip). Apple launched its latest iPhone 6 in China today. According to China Mobile, subscriptions reached 799.13 million, compared to 755.19 million a year ago. That included 244.5 million users of 3G services, and 40.95 million largely on their new TD-LTE network using band 41.
The Nexus 6, by contrast, supports virtually all LTE bands world-wide as well as all three commercially used US 700MHz bands (bands 12, 13, and 17), making the Nexus 6 the very first device to be fully interoperable on the 700MHz band, completely eliminating the interoperability problem with this phone. Sprint plans to support 700 MHz Band 12, and expand its LTE network partnerships to new locations, making it comparable in size and coverage to AT&T and Verizon’s LTE networks.
Verizon and AT&T both told the FCC that compliance with the lower “A Block”, which smaller carriers use in the United States, would not be practical or cost/effectice. Guess that problem was solved when Dish lowered their potential power on the single channel “E Block”. Perhaps adding FirstNet compliance (on Band 14) may also be comparitively easy. Of course they’d have to deal with Motorola Solutions, the part of Motorola not sold to Lenovo.
Motorola Mobility consists of the Mobile Devices business which produces smartphones and the Home business which produces set-top boxes and cable modems. Google sold most of Motorola Mobility to Lenovo for $2.91 billion.
