Question 1

アメリカでは物理SIMとeSIMのどちらを使うべきですか？

Accepted Answer

ご利用の端末によって異なります。eSIMはアクティベーションが迅速で、お使いのスマートフォンが対応していれば最適です。ただし端末がeSIM非対応の場合、オーストラリア・カナダ・英国・ニュージーランドでの米国SIMカードにはSimCornerの物理SIMが最適です。eSIMと同様に、手頃な料金、透明性のある価格設定、全国をカバーする通信環境を提供します。いずれの場合も、当社のトラベルSIM USAならストレスフリーで通信を継続できます。

Question 2

アメリカ、カナダ、メキシコではどこでSIMカードを使用できますか？

Accepted Answer

SimCorner USAのSIMカードは、ハワイを含む全米でシームレスに利用可能です。プランに組み込まれたオプションまたは追加オプションにより、カナダとメキシコへの通信エリアを拡張できます。ニューヨークの探索、ハワイでのリラックス、カナダやメキシコへの国境越えなど、あらゆる場面で最高の地域ネットワークによる安定した通信を保証。高額なローミング料金の心配はありません。

Question 3

どのSIMカードプランが自分に合っているか、どうすればわかりますか？

Accepted Answer

米国プリペイドSIMカードの選択は、データ通信量・通話時間・旅行要件によって異なります。通常利用者は10GBプランが適しており、ヘビーユーザーはデータ無制限の米国旅行用SIMがおすすめです。複数国を訪問する場合は、カナダ/メキシコ追加オプション付きプランを選択してください。迷った場合は、SimCornerの透明性あるプラン詳細（データ容量・通話・ホットスポット・有効期限・端末互換性）を参考に、ご自身の旅行スタイルと端末に合ったプランをお選びください。

Question 4

アメリカへ旅行する前にSIMカードを注文すべきでしょうか？

Accepted Answer

はい。米国向け物理SIMカードをご利用の場合、旅行前にご注文されることを強くお勧めします。旅行前にご注文いただくと、米国SIMカードがご自宅に直接配送されるため、到着後すぐに接続を開始できます。これにより、空港のキオスクでの手間、高額なローミング料金、現地での選択肢の制限といった煩わしさを回避できます。

Question 5

アメリカでは、SIMカードはどの通信事業者のネットワークを利用していますか？

Accepted Answer

SimCornerの米国旅行用SIMカードは、主要米国キャリア（T-Mobile、AT&T、Verizon）に接続し、最高の通信エリアと速度を実現します。各プランでは使用するネットワークと、そのネットワークに対応する端末が明記されています。これにより、お客様が確実に内容を把握できます。高速5G、信頼性の高い全国カバーエリア、カナダ・メキシコ全域でのサポートなど、あらゆるニーズに対応。当社の米国向けSIMカードは、信頼できるネットワークとのみ提携し、確実な旅行中の通信環境を提供します。

Question 6

これらのSIMカードは私の携帯電話で使えますか？

Accepted Answer

SimCorner USAトラベルSIMカードは、米国ネットワーク（AT&T、T-Mobile、Verizon）に対応したSIMロック解除済み端末でご利用いただけます。米国キャリアは他国とは異なるネットワークインフラで運営されている点にご留意ください。そのため、ご購入のプランに対応する端末互換性ガイドを必ずご確認ください。24時間365日対応のカスタマーサポートチームへお問い合わせいただくことも可能です。

Question 7

How easy is it to set up and use my USA SIM card?

Accepted Answer

SimCorner SIM cards are designed for a hassle-free setup. Just insert the travel SIM USA into your unlocked, compatible phone upon arrival, and it will activate automatically when it connects to a local US network. There is no complicated registration or bulky paperwork. With clear instructions included and 24/7 customer support, you will be connected and browsing within minutes of landing.

Question 8

Can I keep my Australian number when using the USA SIM cards?

Accepted Answer

Your new US SIM card from SimCorner will give you a USA number for local calls and texts, but your Australian number can be kept if your device has a dual-SIM setup. It is not recommended unless you need your Australian number still active, as using it can incur roaming charges. However, you won’t have to change your +61 number attached to data apps like WhatsApp, Messenger, or FaceTime. This way, you can stay reachable on your home number without roaming.

Question 9

How do I know if I’ve activated my USA SIM card properly?

Accepted Answer

After inserting the USA prepaid SIM card, your phone will connect to the network, and you will get a welcome message. In some cases, it will note that a top-up has been made. You can disregard this message as it is our activation team loading the plan on your SIM. If you face issues or did not receive this welcome message, our email support is always ready to assist you, be it on a Sunday at 3 AM.

Question 10

My USA SIM card isn’t working. What should I do?

Accepted Answer

First, check that your phone is unlocked and compatible with US networks. Also, make sure that you have switched on mobile data roaming and followed the setup guide as given. If it still isn’t working, contact SimCorner’s support team, and we can check the activation of your SIM—they will walk you through getting your travel SIM USA working quickly.

Question 11

How do I top up the balance on my USA SIM card?

Accepted Answer

Every SimCorner travel SIM USA is prepaid and comes with set data, calls, and validity. While top-ups aren’t available, you can extend usage by purchasing additional SIM card(s) as required. Some US SIM cards also offer add-ons (like Canada/Mexico data or international call packs), but these must be included at the time of purchase—not as a top-up later.

Question 12

Do the USA SIM cards have any expiry date?

Accepted Answer

Yes—each travel SIM USA has a set validity period from the activation date you nominate on the registration page. The validity is 30 days for all American SIM cards. Make sure to align your travel dates with your plan’s coverage window, so as not to waste validity on non-usage days.

Question 13

Can I use any of the USA SIM cards on my tablet / iPad?

Accepted Answer

Yes—SimCorner offers a US SIM card designed for newer iPads and tablets. It provides 15GB and 100GB data options with full hotspot/tethering support. As this SIM card for USA is data-only, it doesn’t include calls or texts, but the same are unrestricted via data-based apps. If you want network-based voice and messaging, choose a regular travel SIM USA. Always check compatibility, especially with iPads, to ensure smooth activation and browsing.

Question 14

Do I get charged international rates when using my USA SIM card?

Accepted Answer

No—you will never face surprise roaming charges with the SIM cards we provide you. All calls, texts, and data usage are included as per your chosen travel SIM USA. Many plans also include or allow add-ons for Canada, Mexico, or international minutes. Everything is prepaid and upfront, so you don’t have to worry about any hidden costs during your travels.

Question 15

Do I get unlimited calls, texts and data with my USA SIM card?

Accepted Answer

Except for one data-only SIM for tablets and iPads, all SimCorner USA travel SIM card plans include calls and texts within the USA (and Hawaii). High-speed data, however, comes with varying allowances like 10GB, 15GB, 25GB, or unlimited, depending on the plan you buy. SimCorner also has unlimited options for the USA, Canada, and Mexico travel, and add-ons for international talk in 70+ countries (with unlimited calls to Australia).

Question 16

I’ve run out of texts, call minutes, and data, but still have credit. Can I still use my phone?

Accepted Answer

If your allowances are exhausted, you won’t be able to use high-speed data. However, your travel SIM USA includes unlimited calls and SMS to USA numbers, so you won’t run out of calls or texts. Furthermore, your number remains active during the validity period, so you can receive incoming calls. You can still use Wi-Fi for apps like WhatsApp or Messenger. To avoid such a situation, it is recommended to purchase a United States SIM card that matches your expected needs.

Question 17

Can I share my data with other devices?

Accepted Answer

Yes—almost all SimCorner USA SIM cards allow hotspot/tethering, letting you share your mobile data with laptops, tablets, or travel companions. Note that our USA T-Mobile SIM Unlimited plan doesn’t support hotspot, while the USA AT&T SIM Unlimited has a 35GB restriction. All remaining travel SIM USA plans allow unrestricted sharing from your applicable data balance.

Question 18

Will I have trouble browsing, streaming and using social media with the USA SIM cards?

Accepted Answer

You won’t face any trouble with our travel SIM USA, unless you are in a very remote area where local coverage itself is weak or heavily congested. With high-speed 4G/5G coverage on leading networks like AT&T, T-Mobile, and Verizon, you can browse, stream, video call, and use social media apps without interruption.

Question 19

Can I make calls and send texts using any of the USA SIM cards?

Accepted Answer

The unlimited calls that come with our US SIM card can only be used to call standard US landlines and mobiles. If in the US and trying to call a US number, then no country code will be required in this instance, unlike with cross-country calling. For international calls, however, we recommend that you use data-based apps such as WhatsApp, Viber, Skype, etc. to make international phone calls rather than adding credit for the same.

Question 20

Where can I use the SIM cards in the USA, Canada, and Mexico?

Accepted Answer

Our USA SIM cards offer coverage not only in the United States but also in Canada and Mexico, making them perfect for multi-country North American travel. Enjoy seamless connectivity as you move between these countries with no need for additional SIMs.

Question 21

What networks is the SIM compatible with within the USA?

Accepted Answer

Our visitor SIM cards for the USA are compatible with either T-Mobile or AT&T, the top mobile providers, so you can rest assured that you will have a reliable connection on your whole trip.

Question 22

Will I have trouble browsing, streaming, and using social media with the USA SIM cards?

Accepted Answer

Not at all. Our USA SIM cards provide high-speed 4G and 5G data for browsing, streaming, and social media use.

Question 23

これらのSIMカードは私の携帯電話で使えますか？

Accepted Answer

The vast majority of newer smartphones are compatible with our SIM cards, but you’ll need to ensure your phone is unlocked and supports the network frequencies used in the USA. If you’re not sure, feel free to check with your carrier or contact our support team for assistance.
