SIM cards – advantages and disadvantages
SIM cards used to be a very important factor a while ago, when there were not so many possibilities for calling international. As new means started to emerge: VoIP, apps that allow communication through the internet, various roaming services and many more; the SIM cards' market seems to be taking a direct hit. Despite that, SIM cards are still a factor of interest in many people's list of options, so they're not completely extinct.
Some briefing on network chips and SIM cards
Dual SIM smartphones seem to be popular in the Asian territory, while in the western side, they seem to be less demanded, as going along with two mobile phones is not inconvenient for some.
When it comes to network chips, there is known to be two kinds, varying from a market to another. Europe and the West has the GSM chips, while in Asia, the CDMA chips are seemingly more popular. On the USA's side however, both GSM (used by AT&T and T-Mobile) and CDMA (from Sprint and Verizon) are available, so the competition goes on.
So, a case like this, leaves a couple of openings for trouble, such as the network-locking. If a phone is locked to a certain network or chip type, it would limit the possibility of using a wider variety of options. Because of this, a considerable part of those who travel abroad are usually buying a side-phone, so it could be equipped with a local SIM for international calling, when they reach their destination. A set of inconveniences are also packed along with this, such as the need for you to manage a second number, and possibly to send notifications to all who might want to reach you; additional costs on your budget as well as the actual, physical management of the phone, such as recharging, carrying, etc. All of the above and possibly many other trouble that could appear along, might encourage some people to use the already existing international calling apps, one of the examples being Nalo.
A nice part of the local SIM card while traveling
While getting a local SIM card, one could benefit of using the local calling prices, along with a service that is much cheaper than the usual roaming prices. An example could be Nalotel, since you could simply use an access code for USA and Canada, and then you are ready to call right away, using the competitive plans or rates provided.
And a counterpart - the downsides
A new number however, would need to be known, therefore, you'll need to make sure that everyone you want to stay in touch with, gets it, which may be a time-consuming task.
Another hindrance could be the foreign language of the visited country. If you don't speak their native language, and English won't work either, it may be difficult to find a proper way to acquire a decent product. But you can always hope for a helping hand from the locals as well.
An easier and viable alternative: Nalotel
With Nalotel, you could freely call your family and friends, if you are in the USA or Canada. There is no need for you to worry about a second SIM or another phone either. All you have to do is to dial a local phone number, and then your desired number; that for the case you are using the services provided by Nalotel.
If you are travelling, there is also the app, called Nalo, available in magazine-play and app store, that you can take advantage of in order to call directly from your cellphone/tablet/ipad, etc. With Nalo, calling other users is free, and reaching a landline or mobile phone is cheap. All you need for that, is credit or an active calling plan. Another reason to try this app, is that you can also avoid the roaming prices by using it.
