Introduction of American Mobile Phone Card Introduction of American Mobile Phone Kaka

Now more and more friends choose to travel to America. Whether traveling or studying abroad, they will face a problem, that is, what should they do if they go to the US phone card? Is the concept of calling card the same as that in China? We know that China now requires real-name registration system to register. What are the rules in America? The following small series will bring you an American mobile phone card strategy.

1, rent WiFi, buy a mobile phone or open international roaming?

If you don't know anything about mobile phones and are too lazy to operate them, rent Wifi. If you are willing to study, it is more appropriate to buy a calling card. Especially for iPhone users, there is basically no adaptation problem, which is most suitable for buying cards. As far as price is concerned, telephone cards are cheap.

1) rent WiFi

Advantages: simple to use, can be used on any mobile phone, and there is no adaptation problem.

Disadvantages: it's a bit troublesome to rent, the equipment is old and easy to break down, and you have to take another charging treasure to charge it.

2) American mobile phone card

Advantages: the price is low, you can call and text, and then throw it away.

Disadvantages: card replacement, mobile phone adaptation problems, some Android phones need to be set online.

3) International roaming

2. Which carrier should I choose in the United States?

Compared with the three major domestic operators, China Mobile, China Unicom and China Telecom, there are many more operators in the United States, including large national operators, small local operators and many virtual operator.

1) national operators

The first echelon is now two major operators, AT & amp； T and Verizon. It has the best network coverage and fast speed. But inaccessible places are generally not covered.

The second echelon includes T-Mobile and Sprint. Poor coverage, no problem in big cities, even worse outside the city.

Verizon and Sprint use CDMA system. American CDMA mobile phones don't have SIM cards. In the past, CDMA mobile phones in China could only roam and could not change numbers. So Verizon and Sprint just ignored it.

Only when &; T and T-Mobile are two major operators. I also saw on Taobao that both operators' cards are sold, and T-Mobile's cards are much cheaper.

T-Mobile's network coverage and AT & amp； T has a gap. The suggestion is that if you mainly stay in big cities, T-Mobile will do. If you are traveling abroad, especially traveling by car, it is recommended to use AT & amp； t .

About T-Mobile and at & amp； T's signal network coverage. I found a map from official website. You can refer to it yourself. The first one is the network coverage map of T-Mobile, and the second one is AT & amp； T's network coverage map, the gap is still very large.

You can also log on to this website directly:/networks/USA/t-mobile-coverage to see if there is operator's network coverage where you want to go. Orange is the place with the strongest signal, and green is the place with the weakest signal.

2) Local operators

There are many others, such as UScellular and LEAP. Basically, don't think about the place you are going unless you are extremely familiar with it.

3) virtual operator

Virtual operator is very common in the world, and there are some in the United States, such as H2Owireless and Red.

Pockets, lycra, etc. The so-called virtual operator does not build its own network. It wholesales some numbers from operators and then retails them to users under its own brand name. So choose virtual operator card should pay attention to is:

First of all, look at which operator's network it uses: the price will generally be cheaper than the operator's, which is normal.

Because operators often guarantee the best service to users, giving users in virtual operator is generally equivalent to second-class citizens.

Under the same conditions, the actual rate of its users is much worse than at&T's own users. See if it supports 4G: America's 4G network has been built for three years and has covered the whole country.

There is also a small trap. Many cards are called "unlimited traffic", but they are all 2G traffic.

At this time, it is necessary to take a closer look at the high-speed 3/4G traffic provided. Such as at & amp； T native card has no unlimited traffic package, and virtual operator card has some unlimited traffic gimmicks, but the actual experience is much worse than native card.

Many virtual business cards are "unlimited international direct dial calls", and there are also traps.

I have personal experience that virtual business cards can make international calls directly, but they are not used at all.

When you are busy, such as at night or all day on weekends, the phone can't get through at all. Even if you get through, the voice quality is unacceptable.

In fact, the so-called direct dial telephone is also an IP telephone, and the capacity of the virtual IP telephone system is definitely insufficient. Therefore, only the native card is directly the operator's system, and the direct dial telephone is guaranteed.

To sum up, most of them are directly purchased &; T's native card is expensive, but if you want to use 4G for free, it is the best choice.

3. How to choose a calling card?

Once the operator has chosen, the card will be easy to choose. Considerations include:

1) price

The cost of re-purchasing at & againT cards in the United States, plus tax, is generally around $70. Domestic prices range from 200 to 500. Search for "American ATT" on Taobao for the specific price.

SIM card ".

2) Confirm whether 3/4G data is supported.

3)SIM type

IPhone5/5S/5C/6/6P uses Nano card; iPhone

Most mobile phones such as 4/4S use Micro cards, commonly known as small cards; Only a few mobile phones still use big cards. So you'd better tell the seller your mobile phone model when you buy it.

4) The card contains packaging.

According to your own itinerary and usage, decide the voice duration, data flow and validity period. Because when traveling abroad, the traffic demand is often greater than that in China, so you can refer to your monthly package traffic in China and increase it appropriately.

5) Internet settings

Some mobile phones need to set an access point (APN). If you find that you can make a phone call in America but can't surf the Internet, don't be nervous. Generally speaking, you need to set up an APN. The setting is very simple, just follow the instructions of the operator.

6) Hotspot function

If you want to share your phone as a hotspot with other devices, you need to turn on the hotspot function. Note: At present, most iPhone cards cannot be ironed, because At & amp； T can be restricted, and hotspots can only share native cards.

7) Call

Call the United States: dial the number directly.

Call China Mobile: 0 1 1+86+ mobile phone number.

Call China fixed line: 0 1 1+86+ area code (excluding 0)+ fixed line number.

Call back to China with T-Mobile card: add 0 1 186 or 0086 or +86 before the number (long press 0 is+).

China calls the American card number: dial 00 1 or+1 (long press 0 is+).

4. Can domestic mobile phones be used in America?

Both telephone and 2G Internet access functions are available, but 3G and 4G Internet access also depends on the specific mobile phone model.
