$24/mo. Ultra Mobile Prepaid Phone Plan with Unlimited Talk, Text and 5GB of 5G • 4G LTE Data (SIM Card Kit)

Esta sim funciona perfectamente en Colombia, recibe y hace llamadas hacia USA, y también recibe mensajes de texto. La recomiendo para quien necesite utilizar un número de USA desde latam, ya que recibe llamadas y mensajes de texto. Útil para verificar cuentas de bancos, de paypal, whasatpp, o cualquier otro tipo de verificación por mensaje de texto

We bought 2 1-month 3G plan SIM cards for our Costa Rica trip. They worked well the first 2 days, however they became totally not functional in a sudden since the 3rd day being activated. We are very sure it's not due to the data running out because each of us only consume 300-400mb the first 2 days. The SIM cards can sometimes detect the local signal, however, no data can be used anyway. It is frustrating to meet this kind of the situation during the trip oversea.Their customer service is useless. The chat window on the official website is a chatbot and not helpful at all. Once you asked to talk to the real person, the window will be gone.They also provided an US number to be reached. However, the SIM card is useless, how can we make the international call?

It’s easy to use

I bought this card for an iPhone. I used it on a trip to three countries. I activated it and it worked perfectly in the United States, both for calls and texts. Then in Colombia it worked, but the calls were very low. The text messages didn't work. Then in Venezuela it was the same as in Colombia, calls with a little difficulty and no text messages. I think it's a good option to not be left without communication if you're going to travel. It's super easy to install the SIM card, the app and control the recharges.

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.

The coverage by T-Mobile focuses on busy areas -- they neglect many residential areas and provide only voice and slow data service. "Main street" gets 5 bars but moving away 300m (1/4mi), reception drops down to 1 bar !! And data-speed drops significantly. This doesn't happen in the middle of nowhere -- this happens within 5mi form Apple HQ in Cupertino !!In other parts of the US, I have driven 4+ hours without getting any T-mobile coverage at all. Not even in the hotel in a small town. Local residents told me, I should have used A or V service instead.

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.

Second time buyer and works perfect for travelers, easy install and setup instructions.You can make overseas calls whilst on travel, recommended.

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.

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。

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。
