If I jailbreak my iphone 4s would a foreign sim work on it?

Am leaving the country next week and am aware a foreign sim card won't work on my iphone… So I wanna know if I jailbreak my iphone would a foreign sim card work on it

If it's done properly as long as it has a SIM card it will work anywhere with any SIM card. If you need to unlock it it'd be the safest bet. Try releasemycode.com they charge I think $20 now with a promo code they give you in the beginning window.

  • Will out of contract Verizon iPhone4s work with foreign sim? I'm traveling to England for about two months and I would like to take a smartphone. However I have AT&T iPhone 4s and it is not out of contract therefore I can't get it unlocked and put in a SIM card from the UK. My friend has offered me her old iPhone 4s and she is with Verizon. I'm not familiar with Verizon at all so I'm not sure if I can slap a SIM card in there or if Verizon will unlock it if I call and get the codes like I could with AT&T.
  • Why doesn't apple have their own foreign factories? The other tech manufacturers have their own factories, especially Samsung that makes some parts for the iPhone. Why doesn't apple hire people with a lot of knowledge in opening factories in foreign countries and then open their own factory to make even more money?
  • What is the best option for mobile internet for a foreign traveller in the USA? Next month I'm going to make a roadtrip through the USA for 21 days. Now, I'd like to have mobile internet (3G or 4G/LTE) during my whole trip. Preferably about 1 to 2 GB for not more than a total of $50. I'll travel through CA, NV, AZ and FL (start in San Fransisco) and I prefer a sim-only prepaid card. I can't find helpful information on the websites of AT&T, Verizon or T-Mobile. I only can find plans including a phone. I've got an iPhone 5s GSM (A1457).
