There are a few things you can try, in case you haven’t already. Log onto your public mobile account and look at your plan, make sure data is part of your plan and find out if you are prepaid or postpaid because I know with some companies your data will not work if you are postpaid. Second, you can check if you are in public mobiles coverage zone. Third, if the above two are true then you can go to settings on your phone, for example in an iPhone, go to settings>cellular then turn on cellular data. Fourth, if data is turned on as in step three, try turning it off then on again. Fifth, if this still did not work, update and restart your device and check your settings again to see if cellular data is still on. Sixth, if not then try turn off data then back on again before the next steps. Seven, try your SIM card in another phone which you know has working data. Eight, if data works in this other phone then it’s possible that your phone is the problem. Nine, before thinking you should bring in your phone for repairs, try someone elses SIM card in your phone and see if you can use the data. If this still does not work, see if you can get a replacement SIM card at no cost, if not then I’m not really sure it worth paying for a new one because if you tried all the previous steps, it might have already eliminated the SIM card being responsible for your data problems. If you do still want to try a new SIM card, and your data still does not work, you can also cancel the data portion of your plan or switch to a non data plan on your public mobile account. At least, until you find a new phone if you still require data. Good luck! Hope this works for you!:)
