Tello Mobile - US Prepaid SIM Card (3 in 1) | Bring Your Own Phone Kit | Phone Plans Starting at $5/mo up to $25/mo | Nation-Wide 4G LTE/5G Coverage

TMO network, which isn't great in my area of rural appalachia. Cheap however. Moving from cricket as they kept jacking up rates and running out of data. Tello gives me 50GB of data a month compared to only 3gb from cricket and costs way less cricket was 35/month plus a 5 hey you didn't renew on-time fee so basically $40 a month where Tello is only $25/month after the promo ends. I DO NOT like that I don't receive texts when I come back off airplane mode or out of signal, like they aren't stored or resent, if you don't have your phone on and have a signal you aren't getting the text, even later. So, it's cheap and I have tons of data however the tmo signal sucks here and I'm always missing texts from my wife however I do have an excuse now. I guess check their service map before buying. Setup was quick and I ported my number, took maybe 15 minutes from loading the sim to having my number ported to it and making calls. If you're in a city go for it, I have no regrets even with their not great reception in my holler. Once you get to town 5g everywhere.

Very happy with my new Tello service. Once I had my account and pin from my Verizon service reseller and provided that to Tello on their website...it only took 2 mins to port my phone number over! Signal uses TMobile, and that to has been working great, such that I can even get a strong 4G and even 5G service when shopping in the orange box hardware store or warehouse clubs, which I wasn't able to consistently use before. TM has made huge improvements in coverage since I last used them 18 years ago. Lots of data for a low price too and convenient month to month use. 5 stars all around for Tello!

I live overseas most of the time. Tello makes it easy to have cell access when I'm 'home.' Super easy to set up, and I love that if you run out of data, you can just start a new month. Really easy to customize your plan. From what I can tell, it's the cheapest way to have connection.

I picked up this sim with the intenion of getting the "unlimited" plan (That turns out to be 50gb.., then you're shunted to 600k/s) to use for basic internet access, and to keep a handful of devices time and data synced with some services on the internet. Very low usage, basic stuff - no streaming, no music nothing like that. I got the sim on Wednesday, tested it all, and great speeds, 200 down, 40 up. amazing. Went on-site Friday, tested speeds, 50down 10up (I was pretty far from a tower, and I expected this). Used it all day, did some low bitrate music streaming because my Verizon phone had no coverage, works good. Saturday rolls around and I get 1k/s. Can't open webpages, can't ping/traceroute anywhere. Time is not synchronizing - but the signal is the same. Reboot the device, I get 3-4mb for a fracion of a second then it dies. Pings work the same way. I get home today, do some digging - turns out Tello is pretty much on the bottom of the de-prioritization list with T-mobile. If you check out the tello subreddit there's multiple people talking about this. I guess I should have done my homework more. TL:DR: Tello is cheap for a reason. You'll get de prioritized so you can't make calls,use data,text and nobody cares.

The SIM card itself is a good buy and fast delivery So though this review should only reflect this product and seller which gets five stars all the way, the Tello service is another story. It’s a great service that is affordable and super easy to set up. But the only complaint I have is a huge one that makes me regret ever trying them. They throttle your data down to super slow prehistoric speed after only about a week of normal average use. They slow it down so bad just opening up an app you attempt to use takes four minutes even if it ever does open it which it most likely WONT. Your phone will become next to useless except for basic text messages and calls. Sending a video or even just a plain photo thru text at the very end of your billing cycle just plain old WONT happen. It becomes so insanely frustrating when ur not home on your Wi-Fi and u need to do something super important like check your bank account app asap and u just won’t be able to do it. And I have a new iPhone so it’s not my phone. Sucks because it works so so well and so fast in the beginning of my billing cycle. If I were you reading this review and you’re dead set on trying them, I would purchase one month pay as you go style they offer of “unlimited” data for $25 and then you can decide weather or not it fits your needs. But in my opinion, unless you do nothing but call and sometimes send basic text messages, you will not be happy with this service. How they stay in business is beyond me. It’s god awful. Hope this helped…. Mind you this is not the first cheaper and less known cell provider I have tried. They are all like this. I had to finally give in and go way out of my budget and sign up for Verizon’s cell service which is damn near a hundred a month (with phone insurance) just to be able to use my phone as it works at home on Wi-Fi. It works AMAZING now. I can do anything I want at anytime from anywhere I would possibly go. I will just have to bite the bullet here on this one and live with the adjustment I have to make on my budget. Sad.

Updated review: Why I wanted this SIM card for Tello? I decided to go with Tello to replace my landline phone. All I need is calling and voice messaging. Since I was a V customer for almost 12 years, I was told I qualified for a bring your own phone 2nd line paying only surcharges and taxes for 3 years. Great deal right? Oh yes - I forgot "if it sounds too good to be true it, probably isn't true". So, I am now going with a phone ordered on Amazon with this very inexpensive SIM on Amazon. Too my amazement- the price was NOT too good to be true. The only downside of this SIM card was getting it inserted into the correct slot. It took me too much time to get into the correct slot. Finally, I got it inserted. The instructions are limited. Customer support took me to Tello's website that only explains how to activate the cards once it is in the phone. That said...the card is inexpensive and once inserted into the correct slot it was good to go with online activation. If I was elderly and needed this phone, I doubt I could insert the card alone. I am thinking of my father. The online activation went smoothly. I have received an email saying I my phone is ready to function in about 24 hours. I am actually relieved for the 24 hour time delay because it turns out the phone will not turn on because it does not fully charge. I am receiving a replacement phone from Amazon early tomorrow morning. I am so grateful for the real person with Amazon Customer Service. I will try the phone tomorrow. I have no reason to doubt this SIM will work. What a relief and easy process to find an inexpensive Tello SIM card to use for Tello's $5 per month phone plan on Amazon.

Tello is great. It uses t-mobile towers. Set up was very simple and easy. Plans offer great deals.

Wonderful service, easy setup. I use a Pixel 8A with Google Fi but I wanted a local burner type number for my travels. Amazon had this thing to me in a day, I popped out the micro SIM from the card, placed it in the tray, turned my phone back on and then I had two services, Google Fi and Tello. Note, on my phone with texting, Tello is SIM number one, Google is SIM number 2. Pay attention to that. I did not have a service plan but rather I just paid $20 for pay-as-you-go. Save 800 as Tello in contacts, so when you want to know your balance you just text the word BALANCE to Tello, and it will give you what you are looking for. You can use the Tello app, but I just use my regular phone dialer and have a choice whenever I want to make a call or text. Data still comes from Google Fi. As of this writing, texts are one Cent a piece, and domestic calls are one Cent a minute for pay as you go. I think that's reasonable, especially considering privacy. One minor point, for the two weeks I've used this number I've had two spam calls already. But I just block them. Only one person had my number. If you're not going to use Tello for a while, just deactivate it in settings, pull down your menu, hit the little gear, and then in the search block for settings, type SIMs. This is for Android only- I know nothing about Apple. The bottom line this is a convenient way to add a second line to your cellular telephone. The only upgrade you could possibly do is have this service as an eSim but I don't know if that would conflict with the primary eSIM so this physical alternative is adequate.
