What is difference between international unlocked and US factory unlocked smartphones?
International unlocked phones are usually allowed to work with any SIM card in the world, except domestic SIM cards other than the one from the original network carrier of the phone. Factory unlocked phones can be used anywhere they came unlocked from the factory and don't have any network restrictions. If one needs to unlock a phone there are several ways:You can ask your current carrier to unlock it. The law says they are obliged to do it, but the bad thing is that your phone must NOT be under contract.You can go to repair shop. They will unlock your phone by cable using a special software. The bad thing is that you have to leave your phone there for a few hours.You can use a third party phone unlocking service like https://www.unlockradar.com or https://www.unlockplus.com. They will search and provide you with an genuine unlock code from the manufacturer's database. This is the safest method to unlock any phone.Unlock Phone | Unlock Codes | Cell Phone Unlocking - UnlockRadar
Is Tesco Mobile GSM or CDMA UK and Can I buy an iPhone 5s with it UK?
CDMA is in the main the USA CDMA phone do NOT have a sim card slots the phone is activated by the network There are NO CDMA networks Europe! it is 100 % GSM ie simcard so unlocked phones and local sim card for travellers. From the IP4S onwards iPhones are what is know as "World Phones" having BOTH GSM & CDMA functionality So if Apple store Westfield UK has the IP5S and you decide to the US as in A, ( NOT US being me and my family showing off you new phone NO way will that be tolerated) you can with an unlocked IP5S use any of the US networks either GSM or CDMA
I am getting an iPhone 7 from USA. Will it work in India?
Phones in the US are more often sold with contract of telcos. These contracted phones are much less expensive than those in the market. But, they are network locked - meaning no other SIM other than that of the contracted network (like Verizon, At&t) will work on it. Thus, these won't accept any Indian SIM cards.Any network locked phone can be unlocked from most local phone shops or just by simple YouTube vidoes. But, there may be the branding and some apps of the original carrier left in your phone. This too can be removed by jailbreaking the iPhone.Another aspect is that, make sure that the phone runs GSM network and NOT CDMA. Currently, only Docomo & BSNL run CDMA and this is quite outdated in India. Also verify it supports the network frequencies (900/1800/2100/2300MHz) available in India.Make sure it's the original iPhone itself and not any clone. A clone appears exactly the same as the original and may even seem to run same iOS initially. But these are cheap Chinese stuff. If you are getting the phone from your friend/relative you can ignore this.Edit4. Warranty - You may not get this. But you can certainly pay and repair at apple service centres in India or purchase one with premium international warranty (apple care+). Do check with apple official site as my knowledge is limited here.
I dropped my iphone in water and now it won't turn off?
Hello. As I said, I dropped my iPhone 4s in water several hours ago, and since then, it's been in and out of a bag of rice. It's been working fine, except it randomly restarts itself, and if I try to turn it off, it just comes right back on. How long should I keep it in the rice, and would letting the battery run dead help with the power issue?
Samsung J7 integrity verification failed?
Ok so it's been a few months since I got this Samsung Galaxy J7, the model is J700T. One night, i was charging it to be awoken when I suddenly heard the T Mobile sound you hear when the phone is turned on. I check my phone to see a black screen that says something about the device's integrity verification failing, and that I needed to factory reset my device, so I did. Then, again, a few days later, it happened again, no matter how many times I factory reset. When it happens, it usually starts when I plug my phone into the charger, usually at night. Then first, the phone would turn off by itself, and turn on again. A few seconds later, it would reboot again, and it would continue to do so, even if I took the battery out or cleared the cache partition. Then, as it is continuosly rebooting, from time to time, the verification failed message would pop up again, telling me to factory reset. The only way it would stop is if I just leave the phone off for a while, and turn it on later. I'm tires of this occuring almost every day. Is there a solution to this? What do you think caused this issue? I searched it before, and didn't find anyone else experiencing the same issue as me. Should I just bring it to T Mobile and get a new device?
