Need to make a phone call but your phone is experiencing problems? Maybe you need to buy a decent-budget smartphone to make calls without any problems, right?
All mobile phone comes with a mobile network connection that allows owners to make calls to anyone not located outside their network coverage; these mobile phones operate through various types of technologies. Different network service providers often do not make use of the same mobile network technology, and this is why a phone that is on a particular network is unsuited for another network. By so doing, the different service providers make their exclusive offers to customers.
Below are the four mobile network types smartphone developers and carriers commonly use today:
|GSM||GSM stands for Global System for Mobile network. It is the most frequently used mobile network globally. As we have mentioned above, AT&T and T-Mobile function on the GSM network. A few more technologies that are incorporated into the GSM standard include GPRS and EDGE. These provide faster transfer of data on 2G GSM networks known as High-Speed Downlink Packet Access abbreviated as HSDPA.|
|CDMA||CDMA stands for Code Division Multiple Access. It is a more recent mobile network technology that comes with a greater capacity for data transmission. Providers that operate on CDMA networks are Verizon and Sprint Nextel. For the 3G CDMA standard, the incorporated technology is the Evolution-Data Optimized or EV-DO.|
|LTE||LTE stands for Long Term Evolution. It is the most recent generation of cellular technology referred to as 4G.|
|WiMAX||WiMAX is another new entrant in the mobile technology world. It is a close competitor of LTE and the first 4G network developed by Sprint. The HTC Evo was the first 4G phone they developed.|
You won’t normally use a phone made on the GSM network or one that was designed for the CDMA network and vice versa. In the USA for instance, Sprint and Verizon operate through the CDMA networks whereas AT&T and T-Mobile operate through the GSM network. Ting, on the other hand, runs on a hybrid model. It can work on the GSM network or on the CDMA network.
Here are easy ways for you to immediately resolve the “cellular network not available for voice calls” error message on your phone.
A mobile network should not be confused with a wireless network. On one hand, a mobile network pertains to a communications network spread out over an area and is connected wirelessly by transceivers like cell sites. Cellular carriers have cell sites everywhere, enabling them to deliver mobile carrier signals and mobile networks. Herein lies our first fix — your mobile phone can send/receive messages and calls if it’s connected to a mobile network through a SIM card.
Hence, if you are getting the “cellular network not available for voice calls” error message, one good place to start looking into is whether you were able to insert and position your SIM card properly into its slot. Modern smartphones now use a SIM tray that can be accessed by pushing a small hole with a pin to eject the tray. Make sure the SIM card is placed well within the tray before pushing it back inside.
Once you have re-inserted your SIM card, perform a quick restart just to make sure you eliminated faulty background operations which could impede you from making or receiving calls and texts.
For iPhone, simply long press the lock button on the right-hand side of the device and slide the power slider to the right when it appears.
For Samsung phones, long press the lock button on the right side of the device then tap on Restart.
Once your device reboots, try to see whether you are still getting the “cellular network not available for voice calls” error message. If so, you can follow the next steps we have.
Sometimes, due to glitches or weird happenstance, your phone’s network selection gets it wrong. This means while you have, for example, an AT&T sim yet your selection is set to Verizon. The best way to fix this is by setting your network selection to automatic to start using your carrier’s services again.
|1. Open the Settings app then select Connections.
2. Tap on Mobile Networks then select Network Operators.
3. Make sure the switch for Select Automatically is on (in blue).

It is common knowledge that bugs can actually cause havoc on how your phone functions. Sometimes, bugs can also cause why you may be getting the “cellular network not available for voice calls” error message. Fortunately, both iOS and Android developers aren’t tone-deaf when users report issues such as this. As a result, developers roll out updates immediately to address this and other glaring issues.

Faulty SIM cards could also be the culprit when getting a cell network not available error message, which results in your inability to make or receive voice calls. Damaged SIM cards are easy to spot; you’ll know your SIM is no longer up to scratch when checking your phone’s status bar and it would indicate No SIM Card despite having one in the tray.
To isolate the problem, simply remove the SIM card from your SIM tray and try inserting a different SIM. When that fixes the problem, then it’s time to make a switch to fix the problem.
More rarely but not impossible, carriers perform maintenance that renders their services temporarily unavailable. This could very much be the reason why, at the moment, you were getting the “cellular network not available for voice calls” error message and you are not able to make or receive calls.
Fortunately, there is an easy way to check whether your carrier is performing system maintenance.
