Can you update android without sim card
Update at&t blackberry priv without at&t sim card
Samsung is a company that specializes in I had been attempting to upgrade my AT&T S4 to Lollipop, despite the fact that it no longer has a SIM card. However, I kept getting a “Update interrupted” error, and it kept telling me that there were no updates available. That was not a problem because I had 6GB of free space. Then I came across an AT&T forum post that mentioned that in order to get ota, you must have an active AT&T sim card. I inserted my AT&T SIM card, and lo and behold, there’s a 900MB update. A guy tried an old AT&T SIM and it didn’t fit, so it should be an active SIM card, according to a post in r/galaxyS4. What a bunch of unadulterated nonsense! This PSA is for those who are considering switching to TMobile or another carrier and think they will have a simple life. You can’t do it. Avoid AT&T devices, particularly Samsung ones.

How to force an ota update on android
My query is as follows: Will I be able to turn on and use a new unlocked Android smartphone purchased from Ebay without first inserting a SIM card, effectively treating it as an iPod Touch? And you just use WiFi? Please answer as soon as possible. Thank you.
Since the WiFi signal comes from a source other than the SIM card (a modem), you will be able to link to WiFi without getting a SIM card installed in your unlocked android device. Additionally, since you will have a data connection via WiFi, you will be able to run apps that need internet to function. Remember that WiFi is a form of local area network (LAN), and that by connecting to it, you will be able to access the data available on that LAN; however, your computer must have the WiFi function activated.
Purchasing an unlocked device basically means that you can use any SIM card in it, or in other words, the handset is not limited to operating with a single carrier. You can only “enable” the phone’s access to large networks; firmware features such as wifi are unaffected by activation; to use those features, simply charge and turn on your phone.

In order to attract more customers to their service, wireless providers will retain a range of promotions for a smartphone during its life cycle. Often these are sold at a profit, but other times they are sold at such a low cost that the company hopes to make up for it with monthly wireless plan fees. These companies aim to keep you tethered to their service by forcing you to have a SIM card from them in your phone. Although this isn’t true for all wireless providers, it is true for others.
This guide would also be helpful for those who do not have a stable WiFi link. These new OTA updates can be several gigabytes in size, and sluggish or spotty WiFi networks can take hours to download, only to discover that it failed near the end. Using the Samsung Smart Switch PC software, we’ll be downloading a new OTA update on the Galaxy S9 or Galaxy S9+ today.
The actual update procedure would be the same as if you downloaded the OTA update via WiFi. The installation process remains the same; however, the way the update is transmitted to the Galaxy S9 or Galaxy S9+ has changed. As previously mentioned, there are two methods for manually installing a new update on the handset. There is a third approach that uses Odin, but it wipes your computer clean, which while some people like, isn’t the best option.

I’d like to move some information between two Android phones. I know I can do this with WiFi and Bluetooth, but their range is far narrower than GSM’s. I’m curious if I could do this with the GSM module directly.
A SIM’s role, as far as I’m aware, is not to provide transmission but rather to provide identification. It enables the phone to verify its identity with a provider and decode signals transmitted over that network. The phone has the necessary hardware to send and receive signals. So, if a phone isn’t registered on the network, it can still receive signals going around it (though it can choose not to do so for the sake of efficiency), but it won’t understand them because it can’t decode them.
Note: I understand that what is being requested here might not be possible to implement right away with the regular Android SDK. But since this is for research and DIY ventures, I’m fine with working with a rooted phone and performing hacks.
No, it’s not real. This isn’t feasible. GSM or CDMA, or Radio Access Network technology, is just one component of cellular technologies. In cellular technologies, there are two main parts: the Access Network (BTS or NodeB (UMTS), RNC (UMTS), and RAN technology) and the Core Network, which includes components such as Service GPRS Support Node (SGSN) and Gateway GPRS Support Node (GGSN) in GPRS and UMTS, among other functional components.
