Network Locked SIM Card Inserted On Your Tecno Spark 20C Phone? Unlock It Now

Carriers provide cellular connections so you can access the Internet, send text messages, and make phone calls without Wi-Fi. You cannot escape the carriers once you begin using a cell phone.

Customers can purchase a new handset via carriers or the mobile phone market. You may need an unlocked phone if you wish to use a different carrier’s service on your smartphone. However, if you want a gadget linked to a specific SIM card, you may buy one from the carriers for a reduced price.

Part 1: What Does It Mean If Your Tecno Spark 20C Asks for SIM Network PIN?

When your phone prompts you to enter a SIM Network Unlock PIN, it means that your device is currently locked to a specific mobile network carrier, and it can only be used with SIM cards from that carrier. This locking mechanism is usually put in place by the carrier or the phone manufacturer to ensure that you continue to use their services, typically for the duration of a contract. As a result, your phone cannot be freely used with SIM cards from other carriers until it’s unlocked using the correct PIN or code.

Part 2: Why Does Your Tecno Spark 20C Say Invalid SIM Card – Network Locked SIM Card Inserted?

System Errors

Since SIM locking is a smartphone restriction implemented to stop it from being used on other networks, Android system errors can cause network-locked SIM cards. Resetting these errors can help unlock your network locked SIM card inserted device. Service providers decided to provide a formal SIM unlocking option as a result.

Because of this, any locked SIM may be readily unlocked, and once a device opens, it can work like a conventional mobile phone and with any SIM card of the user’s choosing.

Carrier Lock

The consumer must stick with the same service provider for a specific time after purchasing the bundled device and data pack. This is called a carrier lock on the Tecno Spark 20C device and is one of the most common errors in network locked SIM card inserted devices. During that time, the Tecno Spark 20C device will be network- or SIM-locked, prohibiting the user from changing service providers.

The user cannot change the SIM. The service provider will offer the SIM Unlock code needed to unlock the handset when the contract expires. The gadget can be used with any other SIM card and exported to another country without problems when the network lock has been removed.

Region Lock

Apple and AT&T initially worked together to implement the SIM lock and the SIM locked devices. The original purpose was to force the user to continue using the same service provider in a specific area or time.

However, some telecom service providers sell the handsets with select data plans as bundled plans in collaboration with the Tecno Spark 20C device manufacturers. As a result, the handset will cost less than it would otherwise. Sometimes, these offers are particular to a specific region, called a carrier lock.

Firmware Problems

Sometimes, the Tecno Spark 20C device manufacturers release many versions of the same firmware for different geographical locations.

As a result, it may be possible that the user may face contradictions in the agreement of device firmware and the network-locked SIM card that was supposed to be used on the Tecno Spark 20C device. Due to firmware problems, the users may also face a network-locked SIM card-inserted device.

Part 4: Why is SIM Unlocking Important?

As previously stated, a SIM lock enables a service provider to stop a customer from using the smartphone with the SIM cards of another service provider. This guarantees that the Tecno Spark 20C device is only being used with the original SIM card for each provider. This locking also has a lot of drawbacks because it is incompatible with any other SIM card.

1. The phone cannot be used with other SIM cards if the SIM lock is enabled. Customers must therefore adhere to the current plan as is.
2. Since nobody wants to purchase a locked phone, it is hard for someone to sell or gift the mobile.
3. Traveling abroad with a SIM-locked phone could provide some challenges because you won’t be able to use a local SIM card on the phone while you’re there.

All the problems can be fixed, and the SIM works in any nation with the removed SIM lock.

Conclusion

Any of the methods above can work to get around the prohibition against using other SIM cards with your Android handset. The best thing about using Dr.Fone-Screen Unlock is that you don’t need unlocking codes to complete the tasks.

How to Unlock SIM Card on Tecno Spark 20C online without jailbreak

Isn’t it so frustrating when you try to change your SIM or your network, but just can’t because your phone is locked under contract? Phones are our life source in this global age, it’s our tether to reality, to the world! But if you have a carrier locked phone, then that connection is basically under contract by an external agency! You can’t change your networks, there are limitations on how you use your phone, and when you have to travel abroad you have no option other than paying the roaming charges. If you, say, have an iPhone 5c and have these frustrations, it’s likely you’re already wondering how to unlock the iPhone 5c.

Chances are that if you’ve had a carrier locked phone for a while, you might have already forgotten what cellular freedom feels like. But we’re here to remind you. All you have to do is break that carrier-lock, and you’re good to go. However, you should be careful when doing so, cause if you try using a jailbreaking technique, it could have major repercussions. So we’re here to give you some valuable advice about how to unlock iPhone 5, iPhone 5c, or even Android phones.

Part 1: Unlock SIM Card on Tecno Spark 20C via jailbreak

Before we get into telling you how to unlock iPhone 5, or the SIM Card on iPhone or Android, we should first tell you what Jailbreaking is. You might have heard of this term before, and I’m sure it sounded ominous to you. Jailbreak? It sounds awfully close to ‘Prison break.’ Well, considering the carrier lock is sort of like a prison for your cell, it is an accurate terminology. But Jailbreak isn’t just about breaking the carrier lock. That might happen as a by-product, but the real purpose is to break free of the software restrictions which are generally applied to Apple devices. This might seem like a good option because, well, who doesn’t want to break free of all of Apple’s restrictions? But that always comes at several heavy risks.

Threats of unlocking SIM via Jailbreak

1. Not Permanent

This has got to be one of the biggest reasons for not jailbreaking your phone. It is not at all permanent! In fact, the moment you update your system, your jailbreak is lost and if you’ve started using a different SIM it will no longer function, and you’re gonna have to go back to using that Carrier you tried so hard to escape from! It’s really not worth the effort. Of course, you could stop updating altogether, but then that will bring us to…

2. Risky

If you don’t update your iOS, or Mac or iPad or any device at all, in this day and age, you’re basically just asking to be hacked. That is not to excuse those who do the hacking and plant malware on your system, but if you leave your front door open in a shitty neighborhood, well then you only have yourself to blame once you get robbed!

3. Warranty

Jailbreaking has now become kind-of-legal, in a very tenuous sense, but that doesn’t mean Apple wholeheartedly welcomes jailbreaking. If you do so, you will never again be able to avail of the warranty on your phone. And with the kind of major bucks you have to shell out for those iPhones, you best keep that warranty intact.

4. Lack of Apps

Many top-notch and crucial app companies and organizations simply refuse to make their applications usable in jailbreak phones, as they are extremely risky and prone to hacking. As a result, you would have to rely on a bunch of non-professional apps made by amateurs, which is more likely to put your phone in harm’s way.

5. Bricking

This basically means your whole system may crash and stop functioning. As a result, you’re gonna’ have to restore the whole thing and try to salvage whatever information you can. Now those who do jailbreak regularly will give you all kinds of excuses like it happens only rarely or that you can retrieve your data simply from the cloud, et al. But do you really want to divest all your time and energy trying to fight off malware, backing up all your data, etc, especially when there is a much more convenient option just around the corner?

Didn’t think so.
