So SIM toolkit, which is tied to the SIM card is not the right solution. USSD or SMS services are more portable. Plus all the SIM toolkit apps are developed by the big SIM vendors (Gemalto, G&D/Smarttrust, Oberthur) who are located in Europe or China.
Freezing Cooked Tilapia. Leftover tilapia dishes can be wrapped tightly and frozen. Once in the freezer, the tilapia can remain for up to six months. Fresh tilapia can be stored for up to six months as well.
But can you freeze tamales? Yes, tamales keep so well in the freezer! As long as the dish is prepped and packed properly, tamales will stay fresh for up to 6 months in the freezer with little to no changes in flavor or texture. When kept in the fridge, tamales will only keep for a week or so. One thing to remember when freezing tamales is to cook the dish first prior to freezing. Do not freeze raw or uncooked tamales because this increases the risk of flavor or texture changes. Since the dish is made from uncooked ingredients, they will start degrading even when frozen.
