It was so easy to use!
We've always had a cellphone service provider in the US. But with extended upcoming international travel, we decided to port our numbers over to VOIP providers and eliminate our cell service. This little sim card did the trick for us. It let us keep access to data when we weren't near a wifi source. When we purchased our phones a couple years ago, we made sure that they were unlocked. This made switching from our carrier's sim to this one a snap. We just followed the directions on the package and had data access in no time. We had no tech issues, so I can't rate tech support, but had a great overall experience. Since we had ported our phone numbers over to a wifi service (one to Google voice, the other to iPlum) we still had access to our regular phone numbers, so the one that came with this sim was irrelevant to us. It was really the mobile data we were after. And given how easily this worked, now we know exactly how we'll fill our data needs on any trips back to the US. 👍 Yay!

Illegal advertising by seller. Terrible Service
Illegal advertising by seller. Package front and back both state: "Unlimited Talk, Text, & Data". But on the front bottom, it states, "3G Data", and the listing details state: "3GB of High-Speed 5G 4G LTE Data." How can it be limited to 3G of data if it clearly states "unlimited data" on the package front and back. I contacted the seller, Ultra Mobile" about this and asked the same question. They referred me to Amazon to complain to you, if I received the wrong SIM card. However, I was starting to message back to them in the chat that I did not get the wrong SIM, I got the one I ordered, but the seller has put misleading info on the package. Before I could even send that reply message, the chat rep from Ultra Mobile ended the chat as soon as they sent me the message saying to contact Amazon about it. Set up was very complicated, took a very long time to try and get this all straightened out. The activation instructions said I have to change the settings for Access Point Names, which was a long process. But it also seemed as though the Access Point Names were automatically configured during activation. I am unable to access voicemail unless I reset network settings to factory default settings on my phone, which I don't want to do, since I am only trying out this SIM on my phone, and plan to revert back to my Tracfone network. If I reset network settings, all data, bluetooth, & wifi settings will be deleted. That would mean that when I reinstall the Tracfone card, I will not be able to access my voicemail on that network, plus I won't be able to log into my wifi or use my previously paired bluetooth devices with my phone. When the phone is initially set up, and I call my home phone from the mobile using the SIM card, it comes up as "April Bailey", which is not me. There is no way to resolve or change this. Ultra Mobile said they would escalate that, but I dont know if they will fix it. I have had two chats with their customer service, which both went about 1 hour. The chat reps seem to be chatting with multiple people at the same time, so their responses usually take a very long time & they never admit to chatting with multiple people simultaneously when asked directly about it. They claim they are checking resources or having system issues. Most of the chat time is spent waiting for them to respond. When I asked why the physical packaging says "unlimited data" on the front and back, while the plan says "3GB of data", they could not explain that and told me to contact Amazon, then they dumped me off the chat without warning, which was so rude and unprofessional. Both chat experiences were bad. I did try calling one of the 80 countries and enjoyed the free call and text on that. But I would not recommend this company due to the above issues. I also reported them to Amazon, who said they would escalate the issue of false advertising.

Al instalar la SIM Ultra Mobile como SIM #2 en el celular Xiaomi, en ajustes (settings) aparece T-Mobile. Ultra Mobile es un Mobile Virtual Network Operator (MVNO) que compra y revende cobertura T-Mobile. El 1 de mayo 2024 T-Mobile compró a Ultra Mobile. Compré la SIM con 3GB por $19 mensuales y lo utilicé tres semanas en Texas, Florida, Panamá y Venezuela para llamadas telefónicas, mensajitos, data, WhatsApp etc. En Venezuela, sí recibo mensajitos de claves de bancos, incluyendo BofA y familiares. Con roaming, probé llamanado a USA estando en Panamá y Venezuela. Funciona, pero mejor llamar WhatsApp via WiFi que no tiene costo. A fin de reducir la mensualidad, al vencer el mes, cambié el plan mensual de 3 GB $19 al mínimo, $15 mensual. Al hacer un solo pago de $120 por un año, hay descuento que equivale a precio de $10 mensuales. Ofrecen seis planes. Determine el conveniente según el uso que le va a dar. T-Mobile es mucho más costoso. En Venezuela, Ultra Mobile trabaja con partners Movistar y Digitel, por tanto, nótese que como cualquier celular en Venezuela, depende de la cobertura y congestión del operador local. A veces los mensajitos tardan en llegar a Venezuela, dependiendo de la hora del día. Encuentro que entrando y saliendo de modo avión en el teléfono, y también mensajitos en la app de Google Messages en la computadora con Windows 11, mensajitos parecieran llegar más rápido. Ultra Mobile es buena solución para cobertura internacional, Venezuela incluida.

Four Stars with a Minor Glitch
I purchased this prepaid phone card and have been using it for about a month now. Overall, I'm quite satisfied with my experience, which is why I'm giving it four stars. The card offers excellent call quality. Whether I'm calling family across the country or friends in different states, the connection is clear and stable. There's no annoying static or dropped calls, which is a huge plus for me since I often have long conversations with my loved ones. Another aspect I appreciate is the reasonable pricing. The rate per minute is quite competitive compared to other prepaid options I've tried. I especially like that there are no hidden fees or unexpected charges. What you see is what you pay, which makes budgeting for my calls straightforward. However, there's a minor issue that prevents me from giving it five stars. The balance inquiry process is a bit cumbersome. I have to call a specific number and go through a series of voice prompts just to check how much credit I have left. It would be much more convenient if there was an app or online portal where I could easily manage my account and check my balance without making a call. Despite this small inconvenience, I'm still happy with my purchase and would recommend this prepaid phone card to others looking for a reliable and affordable communication solution.

ロサンゼルス〜サンディエゴ間での利用。主にレンタカーで携帯電話をカーナビとして利用するための購入。 良い点: 日本で開設が可能。サンディエゴサファリパークの様な場所でもスムーズな通信。開通後はSIMロック解除したiPhone8でSIMを差し替えれば直ぐに使用可能。 注意: 周波数帯を確認したつもりであったが、b-mobile4G wifi3では使用できませんでした。

I think Ultra Mobile has great plans however you have to activate them in the US before traveling. They will not activate in Canada. This trial kit does not work in Canada.

この商品を購入後、手順どおり設定したが、ハワイでも使用できず、5ヶ月間月額料金がカードから引き落とされてしまいました。 購入は控えた方が良いかと思います

ハワイ旅行に行く前に購入。 不具合があると嫌なので5日前に日本で電話番号を取得して、空港でSiMを入れました。 iPhoneを使用してますが特別な設定も必要なくハワイで通話出来ました。 日本の固定電話にもかけ放題なので留守番をしている家族にも電話をして会話する事も出来て良かったです。 ただ、英語がわからないのに留守番電話が入ってるのは困りました。 恐らく設定に関する内容の自動音声だと思います。 通話出来ると現地ツアーの会社にも連絡が取りやすいので助かります。

特に問題なく使えました。 日本への固定電話が無料が大変便利でした。
