Used in Northern California...no coverage issues whatsoever, even high up in the Sierras. Excellent data speeds. Excellent coverage. Simple to use. But beware of the activation time as its in Australian time. Best to pay for an extra day over your trip. Super happy with this Sim card. Put it in my phone when I landed on SFO and it worked perfectly. Review: Worked perfectly, provided 5g download speeds and at an awesome price - I used this for a 2 week holidy in the USA, spending time in Philadelphia, Virginia and Florida. I set the sim to activate a day early and inserted it into my dual sim Samsung s23 the day I flew out of the UK. Interestingly (to me anyway), even in the UK it connected to a network, reporting as roaming. But I'd not set my phone to use data when roaming so I didn't see if it gave any data in the UK (but I'm pretty sure it wouldn't have). Anyway, upon arrival in Philadelphia it straightaway connected to a 5g network (which was an unexpected benefit as it was only listed as being 4g. Download speeds were excellent (test image attached). It also worked fine for me when I set the phone up as a wifi hotspot, which again was unexpected as some reviews suggested that wouldn't work. The number also worked fine for receiving and making calls, and also for text messages. I've had no trouble with signal strength, although I have for the most part been in reasonably populated areas. All in all though, couldn't be happier. Will absolutely use it for future trips to the USA. ## Features - USA SIM Card: Connect quickly, easily, and securely to your next destination with our USA tourist SIM card.

I purchased a prepaid USA SIM on T-Mobile for a holiday visit. SIM was activated OK but mobile service is terrible and I'm only getting a few kbps making it unusable, voice keeps dropping and phone keeps on disconnecting from network. I'm now forced to go back to roaming on my UK based SIM on T-Mobile but at higher roaming charges, but at least I can get 5G with good throughput and can make calls meaning my phone and network is not the issue, and must be Simcorner as wonder if the prepaid SIM is for basic 2G as I get a few kbps only. I sent numerous emails for support (no way you can actually speak to anyone) but no response whatsoever. I would go as far to say Simcorner is a scam and suggest you avoid and go elsewhere for SIM cards. ## Frequently Bought Together - SimCorner USA Travel SIM – 7 Days Unlimited 5G/4G Data | 3-in-1 (Standard/Micro/Nano) | Calls & Texts to US & Hawaii | T-Mobile Prepaid - UK to US Plug Adaptor - UK to US Plug Adapter 40W USA Travel Adapter from UK for American Canada Thailand Mexico Colombia 4 in 1 USBC Fast Charger with USB C Port for Phone Pad (Type B) Tusreda - Jsdoin UK to US Plug Adaptor 3 pin to 2 Pin Flat Travel Adapter for USA, Canada, Mexico, Thailand, Refer to Description for country list US (2Pack） --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/435259146-simcorner-usa-travel-sim-7-days-unlimited-5g-4g-data](https://www.desertcart.jp/products/435259146-simcorner-usa-travel-sim-7-days-unlimited-5g-4g-data) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-13*
